musl: fix missing <sys/time.h>.

Issue peported by Ethan Hawk. Our socket.c module is using struct
timeval without including <sys/time.h>, which breaks on musl.

* configure: in the select test, let's include <sys/time.h>, and
if the test passes, let's set have_sys_time, so that HAVE_SELECT
implies HAVE_SYS_TIME. This way code wrapped with HAVE_SELECT doesn't
separately have to test for HAVE_SYS_TIME.

* socket.c: If HAVE_SYS_TIME is true, then we include <sys/time.h>,
independently of HAVE_SELECT.
(sock_timeout, sock_load_init): Like the select-based code, code using
SO_SNDTIMEO or SO_RCVTIMO also uses timeval, so needs to be wrapped with
HAVE_SYS_TIME.
