futex: restartable futex_wait
LTP test sigaction_16_24 fails, because it expects sem_wait to be restarted
if SA_RESTART is set. sem_wait is implemented with futex_wait, that
currently doesn't support being restarted. Ulrich confirms that the call
should be restartable.
Implement a restart_block method to handle the relative timeout, and allow
restarts.
