[kvm-unit-tests PATCH v4 05/13] scripts: Add 'kvmtool_params' to test definition

arm/arm64 supports running tests under kvmtool, but kvmtool's syntax for
running and configuring a virtual machine is different to qemu. To run
tests using the automated test infrastructure, add a new test parameter,
'kvmtool_params'. The parameter serves the exact purpose as 'qemu_params',
but using kvmtool's syntax.

Changes v3->v4:
* Added params_name in scripts/common.bash::for_each_unittest() to avoid
checking for $TARGET when deciding to parse kvmtool_params or
{qemu,extra}_params.
* Dropped factoring out parse_opts() in for_each_unittest().
