[PATCH] mergetool: export variables for use by custom mergetools

[David Aguilar <davvid@xxxxxxxxx>]

The MERGED, BACKUP, LOCAL, REMOTE and BASE variables were not being
exported from the git-mergetool.sh script.  This prevented custom
mergetools from being able to use them.

We now export them so that arbitrary mergetools can easily interact
with git mergetool.

This problem was Reported-By: Evgeny <evgeny.zislis@xxxxxxxxx>
