Minor packaging cleanup
zgenhostid
and zvol_wait
are both tools that should be in /sbin
(may be used during early boot, or possibly system recovery). This MR relocates them. It also patches the systemd unit that calls zvol_wait.
Also, this removes another patch, Fix-CONFIG_X86_DEBUG_FPU-build-failure.patch
that is implicated in the SIMD fiasco. Though it probably doesn't harm anything, it is totally worthless. This MR removes that patch.
