timeval: Block SIGALRM when sleeping.

Commit 00a16895 (timeval: Don't require signals for time_alarm().)
Incorrectly disabled signals when when CACHE_TIME was disabled.  In
fact, the reverse was correct.  As a result of this bug, OVS would
wake once every 100ms unnecessarily.  It shouldn't have affected
correctness otherwise.
