Subject: [PATCH 3/3] perf tests: remove getpgrp from mmap-basic

From: Riku Voipio <riku.voipio@...aro.org>

mmap-basic fails on arm64.

 4: read samples using the mmap interface                    :
read samples using the mmap interface: FAILED!

This is because arm64 doesn't come with getpgrp()
syscall. The syscall is a BSD compatibility wrapper,
Archs that don't define __ARCH_WANT_SYS_GETPGRP do
not have this. Remove it, since getpgid is already
used in the testcase.
