composetable: invalidate cache based on symlink mtime too

Browse Source 
When the compose file is a symbolic link, take the link itself's
modification time into account (in addition to its target's) in
determining whether to invalidate the compose cache.

This is useful e.g. on NixOS systems where the compose file might point
to a store path with an irrelevant modification time, and we want the
cache to expire when the symlink itself changes.
