LOG: [NFC][CFI] Avoid clang error in CFI tests (#135981)

In these tests we test correct linking flags set,
and it's confusing that command fails because of
other missing required flags.

Clang diagnostics opportunistically proceed after
error report on required flags, but there is no
guaranty that processing of tested flags are the same
in supported and erroneous flag sets.
