tests: ensure `$PYTHON` is quoted for Windows

Global installs of python3 go into "Program Files", and tons of tests fail with
mysterious errors if this isn't quoted.  Most of this is a followup to
0826d684a1b5, but a some of these were existing issues.  Shebang lines are
ignored because quoting breaks direct execution- these will need to be launched
indirectly with the quoted `$PYTHON` command.
