Set GIT_SSH_VARIANT when setting GIT_SSH

Make it explicit that the ssh wrapper we use for control master
support accepts OpenSSH-compatible command line arguments instead of
asking Git to guess.

The GIT_SSH_VARIANT setting was introduced in Git v2.13.0-rc0~3^2~2
(2017-02-01) as a more reliable detection method than relying on the
ssh command name.  Fortunately the default variant was 'ssh' (i.e.,
OpenSSH-compatible) so this wasn't initially required.

Now Git wants to start using more OpenSSH features
(-o SendEnv=GIT_PROTOCOL), and in order to do so its ssh variant
detection will need to be tweaked.  Set GIT_SSH_VARIANT explicitly
so this helper can continue to work regardless of how Git modifies
its autodetection.
