Subject: [PATCH v3 1/2] perf test workload noploop: Name the noploop process

Name the noploop process "perf-noploop" so that tests can easily check
for its existence.

Signed-off-by: Ian Rogers <irogers@...gle.com>

v3: Switch to using pthread_setname_np rather than prctl as glibc and
    musl having conflicting and mutually broken definitions of which
    header files to #include for prctl. Suggested by Namhyung Kim
    <namhyung@...nel.org>.
