tests/run-tests: avoid C:/ in arguments
MSYS replaces C:/... in arguments with C;... as it interprets the C:/ as a
colon separated POSIX path list. The colon is replaced with ; (path separator
on Windows) according to
http://www.mingw.org/wiki/Posix_path_conversion
So we must not replace \ with / for neither $TESTTMP nor $TESTDIR, but we
have to keep replacing \ with / for the Popen4 call of function hghave. If we
don't do the latter, test-run-tests.t will fail with
$ python run-tests.py --local test-run-tests.t

$ echo skipped

#endif
#if false
An additional tweak in test-ssh.t is needed that globs away an encoded path,
as it can't be translated back to $TESTTMP, because the backslashes in the
output have been already encoded as %5C.
This patch makes test-ssh.t pass in MSYS on Windows.
