[PATCH] mergetool: Use merge.tool config option.

[James Bowes <jbowes@dangerouslyinc.com>]

If no merge program was supplied on the commandline, and the config option
merge.tool was set to a valid value, then mergetool would unset $merge_tool
and instead try to find an installed merge program. This patch removes the code
that unset $merge_tool, so the merge.tool config option will always be used, if
set.
