sysutils/froxlor: Fix packaging when APACHE option is unset

The pkg-plist for some entries relied on the AP_NAME variable, which is
only defined when the APACHE option is set (the default), via
bsd.apache.mk. The variables value is the ports name, so replace it with
PORTNAME accordingly.

While I'm here, fix misspelled PORTREVIION.
