Subject: [PATCH] bump bhyve API version to match stlouis

illumos 18526 (vCPU sets as a vmm type, with `VM_GET_CPUS` accepting
any `cpusetsize` up to a page) bumped `VMM_CURRENT_INTERFACE_VERSION`
to 19 on stlouis, which fails `header-check`. Propolis does not use
`struct vm_cpuset`, so we only need to bump the version.
