rhg: Sort config files when adding a directory
For example in `/etc/mercurial/hgrc.d/` or with `HGRCPATH=some-directory`.
Previously files where parsed in the order returned by the filesystem,
which is undefined. But order is significant when multiple files
define the same configuration key: the "last" one wins.
