Fix PORTSCOUT=ignore:* uses throughout the tree

PORTSCOUT=ignore:1 is the only valid way syntax according to the
Portscout documentation. In disables the distfile version checks
completely. In order to ignore only certain version instead, it is
necessary to use other Portscout keys like skipv.

Also, remove the setting completely when it attempts to instruct
Portscout to skip versions older than the current one.
