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.
