remove unused SIGTIMER handler in timer_create
this was leftover from when the actual SIGEV_THREAD timer logic was in
the signal handler. commit 5b74eed3b301e2227385f3bf26d3bb7c2d822cf8
replaced that with use of sigwaitinfo, with the actual signal left
blocked, so the no-op signal handler was no longer serving any
purpose.
the signal disposition reset to SIG_DFL is still needed, however, in
case we inherited SIG_IGN from a foreign-libc process.
