Subject: keg: handle the info directory file properly

If HOMEBREW_KEEP_INFO environment variable is set:
 - Do not symlink the info directory file (aka 'share/info/dir')
   otherwise it gets overwritten by next installed brew.
 - Install an entry in the directory for each linked info file when the
   brew is linked.
 - Uninstall the entry when the brew is unlinked.

Closes Homebrew/homebrew#9700.
