QDateTimeParser: implement parsing of time-zone specifiers

The serialization of date-times understood time-zones (indicated by a
't' in a format string) but the parsing didn't (so viewed the 't' as a
literal element in the format string, not matched by the actual zone
it needs to parse), although some tests expected it to.
This made round-trip testing fail.

Implemented parsing of time-zones.
Re-enabled the formerly failing tests.

[ChangeLog][QtCore][QDateTime] Added support for parsing of time-zones.
