Remove the timestamp info in genarated files

For moc, rcc and uic, then it's friendly for tools like ccache.
ccache is using md5 to check file modification, but the different
timestamp info will cause different md5 for same meaningful
contents, it will disabled ccache.

Updated the autotest for uic and rcc.
