Since it uses EINVAL unconditionally, it needs to also unconditionally
include errno.h.
Detected when recent changes made errno.h not be included by chance when
tools/perf/arch/arm64/util/unwind-libunwind.c gets included by
tools/perf/util/libunwind/arm64.c.
Putting this changeset just before that change so that we don't lose
bisectability on arm64.
