futility: extract verify_kernel command to an external test

The verify_kernel command is used only in a host-side test. It
doesn't need to be built into futility. This makes it a separate
executable used just for that test.

BUG=chromium:231547
BRANCH=none
TEST=make runtests

Note that the load_kernel_tests.sh still passes, using the
external verify_kernel executable.
