qhelpgenerator: localize SOURCE_DATE_EPOCH to UTC
The SOURCE_DATE_EPOCH environment variable is used as an anchor
timestamp that software builds can use when they embed timestamps
that refer to the build-time into their build artifacts.
The value of the variable is specified[1] as an integer number of
seconds since the Unix epoch (1970-01-01T00:00:00Z).
To ensure that the value is interpreted correctly, and to ensure
that the resulting timestamps embedded by qhelpgenerator cannot
drift with the build environment's timezone settings, we should
store the SOURCE_DATE_EPOCH in QDateTime instances that have a UTC
timezone.
