Replacing PKG_SUFX with PKG_COMPRESSION

[Adam Ciarciński <adam%NetBSD.org@localhost>]

Greetings,

I would like once and for all :) fix the handling of PKG_COMPRESSION. At the 
moment, if only PKG_COMPRESSION has been set, PKG_SUFX always ends up being 
'.tgz'. If there is no objection, I would like to commit the following: [see 
diff below].

Kind regards,
Adam
