Makefile: remove "libnm.actions" explicitly when uninstalling

Fernando Fernández Mancera requested to merge (removed):fix_distclean into master

On Fedora 33 when compiling NetworkManager it is failing with the following error:

ERROR: files left in build directory after distclean:
make[1]: *** [Makefile:18427: distcleancheck] Error 1
make[1]: Leaving directory '/builddir/nm-build/NetworkManager/NetworkManager-1.27.90/_build/sub'
make: *** [Makefile:18356: distcheck] Error 1
Error make distcheck

Adding the file to the DISTCLEANFILES will enforce the removal of this file.
