[LLD] [MinGW] Silence the printouts in one test. NFC.

This particular linker invocation is only run to check that we accept
options, but we don't inspect the generated command line. As all other
commands in the file have their output piped to FileCheck, the lit test
doesn't print any other output; therefore silence this one for consistency
as well.
