[PATCH] fetch2/local: Improve handling of wildcard matches

[Richard Purdie <richard.purdie@linuxfoundation.org>]

Currently wildcard matches end up working by FILESDIR being defined
in the metadata to a default of "." in FILESPATH which is hacky at best.

This patch adds the behaviour into the fetcher so its at least slightly
more explicit.
