signal: Define __ARCH_HAS_SA_RESTORER so we know whether to clear sa_restorer
Vaguely based on upstream commit 574c4866e33d 'consolidate kernel-side
struct sigaction declarations'.
flush_signal_handlers() needs to know whether sigaction::sa_restorer
is defined, not whether SA_RESTORER is defined. Define the
__ARCH_HAS_SA_RESTORER macro to indicate this.
