Followup to r13553 which caused some build failures.

(1) Detect availability of pthread_setname_np. Ignore testcases
    memcheck/tests/threadname[_xml] if not available.
(2) Enable _GNU_SOURCE to avold compiler warnings.
(3) In threadname_xml filter out stackframes referring to system
    libraries. Added tests/filter_xml_frames to do that.
(4) Adjust .exp files as needed
(5) Do not ship stdout.exp for memcheck/tests/threadname[_xml].
