kdump: T8868: skip kdump-tools when no crashkernel= is set

kdump-tools runs early in boot, before the VyOS configuration renders its
defaults file. On a live ISO, or on any system without "system option kdump",
it therefore starts with the Debian default USE_KDUMP=1 and reports
"no crashkernel= parameter in the kernel cmdline ... failed!" on the console.

The service is now only started when a crashkernel= parameter is present on
the kernel command line, which is exactly the case when kdump is configured.

The smoketest previously expected the service to be active right after
commit, which only held because the failing unit still ended up "active".
It now expects the service to run only when booted with crashkernel=.
