Add a test for glnx_shutil_mkdir_p_at with an unusable parent


This is a slight generalization of the reproducer contributed by Will
Thompson: as well as exercising the case where the parent is a dangling
symlink (reproducing GNOME/libglnx#1), this also exercises the case where
the parent is a non-directory non-symlink (in this case a regular file).

Reproduces: GNOME/libglnx#1
