Subject: Tests: Avoid output when running symlink check

Since commit 58d10cf6f1 (Alternative symlink-creating mode for
file(INSTALL ...), 2021-08-02) we test creating a symlink during
configuration to decide whether to activate some tests.  Capture
the process output during the check to avoid leaking the error
message on failure.
