Allow 32-bit builds on Buster. This has some advantages
regarding supported HW accelerations in UltraGrid, eg. h264_omx is not
supported in higher versions of the system.
It is not enabled by default but can be enabled easily by switching the
value in YAML file.

Deleted 2 unneeded lines:
1. OLDPWD - not used
2. comment - no longer valid - the cached environment key contains hash
of .github/scripts/Linux/arm/bootstrap.sh, which means that if the file
changes, the old env is not used, anyways
MMAL headers not present in 64-bit RaspiOS 11 libraspberrypi-dev (but
mmal.pc is still there!)
The MMAL API doesn't seem to be longer supported, see necro-posting
in GH-129.
Own FFmpeg was build only to enable periodic insertion of SPS/PPS NALU
for OMX. This should be now, however, possible to do even with the lavc
`header_inserter` option (which is enabled by default for OMX). Also
the OMX API seems unavailable in more recent RPi OS in favor of other
APIs.
This implies driver version 520 in Linux.
That driver is not avaiable on Kepler cards (1st generation supporting
NVENC), which is almost 10 years old and only basic H.264 was supported
there.
This SDK version allows acceleration of AV1 on supported cards (GeForce
40 series - Ada Lovelace).
This reverts commit e457ab87f7 but the
patch is updated to match current FFmpeg.
The FFmpeg commit that seemed to do the same (7eeef72c6) is not working
correctly because it assigns idrPeriod cc->gopLength, which was set to
NVENC_INFINITE_GOPLENGTH above in case of intra-refresh.

lsb_release command is not always present, even in Ubuntu, wheresas
/etc/lsb-release file is but it isn't necessarily in all distros,
eg. Arch doesn't have it by default.
+ install libdbus-1-dev dependency - not needed for the CI because there
it is at this point already installed but the script can be used also
to setup the environment outside GitHub CI
Since the FFmpeg commit 7eeef72c6, the IDR period is set to gopLength
unconditinally even for intra-refresh mode, which is what the removed
patch did.
+ do not check if FFmpeg is patched (the macro is )
Copy sounfont to known path for macOS and Windows CI builds (in Linux,
this is already handled with a environment var SDL_SOUNDFONTS). And also
use that location if there is any soundfont.
Previously, actually the same version was used but downloaded directly
and installed with dpkg, because it has been used a version from U20
(now default) to U18.
SDL2 now obviously works on U20.04, because we are building there. It
doesn't work on U22.04, but neither the build with SDL 2.0.20 nor 2.26.2
does.
The problem seems actually to be the inclusion of Wayland libraries in
AppImage.
