rG79e57ea662d9: libc: Add "Z" as TZ designator for strptime.

Summary

strptime doesn't currently accept Z as a valid timezone setting. Per ISO8601, the construct to designate UTC time is to add "Z" as the TZ designation. Add support for Z and while we are at it, document the fact we also accept UTC in the manpage.
