devel/qscintilla2*: Forced PORTREVISION bump

Try to overcome the nag emails about version numbers going backwards
bombarding the kde@ list after b7559947.

These origins were once the home of the Qt4 version of qscintilla2
that had PORTEPOCH set, but were deleted so long ago, they even aren't
even in MOVED. Furthurmore, the package names are different.
