executor: sys/linux: Add VCPU fd to `syz_kvm_assert_syzos_uexit`
Enhance the debugging capabilities of C reproducers by passing the VCPU
file descriptor to the syz_kvm_assert_syzos_uexit function. With access to
the VCPU fd, the function can now dump the VCPU's register state upon
assertion failure, providing critical context for debugging guest execution
issues.
