extras/package/snap: Add `layout:` to symlink `/usr/share/libdrm`
When running the VLC snap from the command line, the following error message:
/usr/share/libdrm/amdgpu.ids: No such file or directory
This is due to a missing layout:
field. The program is looking in /usr/share/libdrm/
, but the file is actually in $SNAP/usr/share/libdrm/
, so layout:
allows creating a symlink to this location.
