Get rid of manually adding "nbX" to PKGNAME when a pkg was changed in

pkgsrc. Instead, a new variable PKGREVISION is invented that can get
bumped independent of DISTNAME and PKGNAME.

Example #1:
        DISTNAME=       foo-X.Y
        PKGREVISION=    Z
     => PKGNAME=        foo-X.YnbZ

Example #2:
        DISTNAME=       barthing-X.Y
        PKGNAME=        bar-X.Y
        PKGREVISION=    Z
     => PKGNAME=        bar=X.YnbZ (!)

On subsequent changes, only PKGREVISION needs to be bumped, no more risk
of getting DISTNAME changed accidentally.
