t/t4004-diff-rename-symlink.sh: use three-arg <prereq>

Change the tests that skipped due to unavailable SYMLINKS support to
use the three-arg prereq form of test_expect_success.

This is like the "tests: implicitly skip SYMLINKS tests using
<prereq>" change, but I needed to create an additional test for some
setup code. It's in a separate change as suggested by Jonathan Nieder
for ease of reviewing.

    Probably belongs in a separate patch.  More importantly, it is missing
    &&-chaining (not a regression, but it is best to set a good example).
