tags: don't read .hgtags fnodes from tags cache files

Now that we have a standalone and shared cache for .hgtags fnodes, the
.hgtags fnodes stored in the tags cache files are redundant.

Upcoming patches will change the format of the tags cache files to
remove this data and to improve the validation. To prepare for this, we
change the tags reading code to ignore all but the tip .hgtags fnodes
entries in existing tags cache files.

All fnodes lookups now go through our new shared cache, which is why
test output changed. Format of tags cache files has not yet changed.
