emulators/vmsbackup: Unbreak on F9+

This port really does require infozip, the base unzip fails to
extract with the message, "Invalid central directory signature".
/usr/bin/tar also fails with a similar message.

This source file only needed a couple of minor fixes to build again.
Passes Redports 8x
