(Re-)Move some blueprints to/from craft core

This is needed to make Craft core independent of craft-blueprints-kde

To craft core:

• pkg-config
• msys
• iconv

From craft core:

• help2man

Completely remove:

• peparser (in case it turns out we need it, it should be moved to craft-blueprints-community)

Merge this together with craft-blueprints-kde!520 (merged)
