mergetool--lib: Allow custom commands to override built-ins
Allow users to override the default commands provided by the
mergetools/* scriptlets.
Users occasionally run into problems where they expect to be
able to override the built-in tool names. The documentation
does not explicitly mention that built-ins cannot be overridden,
so it's easy to assume that it should work.
Lift this restriction so that built-in tools are handled the
same way as user-configured tools. Add tests to guarantee this
behavior.
A nice benefit of this change is that it protects users from
having future versions of git trump their custom configuration
with a new built-in tool.
