Makefile: remove "libnm.actions" explicitly when uninstalling
On Fedora 33 when compiling NetworkManager it is failing with the following error:
ERROR: files left in build directory after distclean: ./docs/libnm/libnm.actions make: *** [Makefile:18427: distcleancheck] Error 1 make: 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.
