make alpm_unlock and trans_interrupt async safe

RET_ERR calls _alpm_log which includes calls that are not safe for use
in asynchronous signal handlers (see signal(7)).  Replace it in
functions called from our signal handlers with a new macro
RET_ERR_ASYNC_SAFE which is identical except that it lacks the call to
_alpm_log.
