build_kernel_image: drop nmi_watchdog=

The ",lapic" part was superfluous for a very long time. See, which was reverted at for procedural reasons (the signer didn't
like the new command line). The signer has since been fixed.

The remaining piece (nmi_watchdog=panic)
(a) was never required for non-x86 systems, as they specified the
    "panic" behavior in their kernel configuration instead; and
(b) is no longer required for x86 systems (as of
    for the same reason.

All architectures are consistent now (where hardlockup detectors are
supported), and we can drop the command line entirely.
