moc: Always indentify as moc

External tools might rely on the output of "moc --version" to identify
moc, and, depending on how robust their parsing is, could break if the
reported name does not equal "moc".

Explicitly set the application name to moc, so that even if the moc
binary gets renamed and invoked via a symlink, it will still correctly
identify itself.

This might help with both binaries from the Qt Company's installer, as
well as with distros which rename moc to moc6.

Pick-to: 6.9 6.8 6.5
