lfs: don't automatically exclude '.hg*' files from external tracking

The only reasons I did this in the first place was because tracking externally
seems like it would always be a mistake, and the eol extension does the same
thing.  Yuya and Jun thought it might be better to not do this[1], so I'll defer
to them on this.  If a problem with say, .hgtags or .hgeol does arise, it can be
added back without breaking existing repos.
