[PATCH 1/4] meson: Use has_header_symbol() to check getcpu()

[Akihiko Odaki <akihiko.odaki@daynix.com>]

The use of gnu_source_prefix in the detection of getcpu() was
ineffective because the header file that declares getcpu() when
_GNU_SOURCE is defined was not included. Pass sched.h to
has_header_symbol() so that the existence of the declaration will be
properly checked.
