Fix strptime decode for musl libc

POSIX does not define a %F for strptime[1], but does define %F for
strftime[2]. Afaik most libc's implement %F for both, but musl is very
standards-compliant and does not have %F on strptime, leading to
unparsed message tag times, which causes all backlog sent from bouncer
on startup to have a timestamp of the current time, instead of the
actual timestamp sent.
