Fixes the UG crashes caused by the multiplication of "@executable_path/../libs/" caused by replacing multiple (originally distinct) LC_RPATH values with this one. + removed invalid comment from Makefile (actually was related to "bundle-nolib" target that is no longer present) closes GH-436

## Remove multiple LC_RPATH occurences of @executable_path/../libs/
|

## as can be seen by cmd `otool -l $lib | grep -B 1 -A 2 LC_RPATH`
|

## which seem to be refused by dyld since macOS 15.4 as can be seen
|
|
## here <https://github.com/CESNET/UltraGrid/issues/436>. The multiplied
