bitbake/cooker: Ensure matchFile returns full pathnames

We should always be passing full pathnames around within bitbake. If
a file was referenced as a relative path to the current working
directory, it might not get passed through the abspath call and
hence the cwd would not get added as a prefix.

This change adds a second pass at ensuring we only return absolute paths.
