The --vmm configure option was added to distinguish between the two virtual
machine managers that kvm-unit-tests supports for the arm and arm64
architectures, qemu or kvmtool. There are plans to make kvm-unit-tests work
as an EFI app, which will require changes to the way tests are compiled.
Instead of adding a new configure option specifically for EFI and have it
coexist with --vmm, or overloading the semantics of the existing --vmm
option, let's replace --vmm with the more generic name --target.
Since --target is only valid for arm and arm64, reject the option when it's
specified for another architecture, which is how --vmm should have behaved
from the start.

Changes in v3:
* Using --target for any architecture other than arm and arm64 generates an
error.
* Don't generate the TARGET variable in config.mak for other architectures.
* Cosmetic changes to the commit message.
Changes in v2:
* Removed the RFC tag and cover letter.
* Removed --vmm entirely.
