Define compat version of mkdtemp for systems lacking it

Solaris 9 doesn't have mkdtemp() so we need to emulate it for the
rsync transport implementation.  Since Solaris 9 is lacking this
function we can also reasonably assume it is not available on
Solaris 8 either.  The new Makfile definition NO_MKDTEMP can be
set to enable the git compat version.
