Re: [PATCH v2 3/3] t7800: run --dir-diff tests with and without symlinks

The series looks good, but I can't test it because it does not apply
anywhere here.

Currently the difftool --dir-diff tests may or may not use symlinks
depending on the operating system on which they are run.  In one case
this has caused a test failure to be noticed only on Windows when the
test also fails on Linux when difftool is invoked with --no-symlinks.

Rewrite these tests so that they do not depend on the environment but
run explicitly with both --symlinks and --no-symlinks, protecting the
--symlinks version with a SYMLINKS prerequisite.

At first, I wondered what the point of having --symlinks and --no-symlinks
was when there is no discernable difference. But 1f229345 (difftool: Use
symlinks when diffing against the worktree) makes it pretty clear: It's an
optimization, and --no-symlinks is only intended as an escape hatch.
