py3: quote several instances of $PYTHON for Windows

Python3 lives in Program Files by default.  The last remaining unquoted instance
is in test-hghave.t.  I can't figure out how to quote that, as it either
complains:

    'c:\\Program' is not recognized as an internal or external command,
    operable program or batch file.

or

    $TESTTMP.sh: line 22: "C:/Program Files/Python37/python.exe": $ENOENT$
