OpenBSD 6.9’s <sys/time.h> includes <sys/select.h> which then
includes <signal.h>, which caused coreutils/lib/nproc.c compiles
to fail with "/usr/include/signal.h:57: warning: 'struct
sigaction' declared inside parameter list". Fix this.
* lib/sys_select.in.h [__OpenBSD__]: Simply delegate to the system
header if being included from <sys/time.h>.
