Subject: [PATCH] CI Linux: add /usr/local/lib to LD_LIBRARY_PATH

+ also to LIBRARY_PATH - this will is done also with -L in configure,
probably

Seems like that /usr/local/lib has never been in LD_LIBRARY_PATH and
somehow it didn't matter so far. But with fluidsynth build, we now get
in CI (== also prevents build):
```
ultragrid_acap_fluidsynth.so: libfluidsynth.so.3: cannot open shared object file: No such file or directory
