journal: fail silently in sd_j_sendv() if journal is unavailable
"syslog(3) and sd_journal_print() may largely be used interchangeably functionality-wise" according to sd_journal_print(3). This socket should be always available except in rare circumstatances, and we don't random applications to fail on logging, so let's do what syslog did. The alternative of forcing all callers to do error handling for this rare case doesn't really have any benefits, since if they can't log there isn't much they can do anyway. https://bugzilla.redhat.com/show_bug.cgi?id=1023041
