    qemu: Convert KVMOPTS to PACKAGECONFIG
    
    Move the KVMOPTS configuration checks and option setting to a
    PACKAGECONFIG option.
    
    This also changes the checking of KVM support on the host build machine
    so that it is processed as a PACKAGECONFIG _remove for class-native
    only. The darwin/mingw32 overrides are kept and applied as _remove
    overrides.
