[PATCH] tests: detect that MSYS lacks symlinks

[Peter Rosin]

Hi!

Another case of ln/cp on MSYS.  The test reported ERROR previously (it
terminated early when it failed to create a broken link with
"ln -s none brokenlink"), with this change, it's 36 PASS / 6 SKIP.

Cheers,
Peter

Subject: [PATCH] tests: detect that MSYS lacks symlinks

* tests/self-check-cleanup.tap: Also check if "ln -s" really created a
symlink to cater for MSYS falling back to an ordinary copy.  Also, don't
chmod the symlinks if they were never created.
