'git mergetool --tool-help' only lists builtin tools, not those that the
user has configured via a 'mergetool.<tool>.cmd' config value. Fix this
by inspecting the tools configured in this way and adding them to the
available and unavailable lists before displaying them.

After the recent changes to mergetool, do we want to do something like
this as well, so that 'git mergetool --tool-help' will display any tools
configured by the user/system administrator?
This is on top of jk/mergetool.
