    release/Makefile.vm: Rework emulator-portinstall
    
    The emulator-portinstall target now unconditionally ensures that qemu
    is installed; but is only invoked if needed (aka. when cross building
    VM images).
    
    MFC After:      3 days
    MFC With:       97bd53ef4d20 ("Fix duplicate rc.conf files")
    
    (cherry picked from commit 7d0ee5ebd052d35e323f2d303e467c2cf305ca39)
