Make tramp-tests.el more robust on w32

* test/lisp/net/tramp-tests.el (tramp-test21-file-links):
Do not call `make-symbolic-link' on w32.
(tramp-test36-find-backup-file-name): Call also
`convert-standard-filename' due to w32.
(tramp--test-windows-nt): New defun.
(tramp-test42-auto-load, tramp-test42-delay-load)
(tramp-test42-recursive-load, tramp-test42-remote-load-path):
Quote command due to w32.
