nixos/tests/misc: Fix reboot-wtmp subtest
From commit b63f65aea0dea11c20e9299210af1d2ee4299b58:

  I used tmpfiles.d instead of activation snippets to create the logs.
  It's good enough for upstream and other distros; it's probably good
  enough for us.

The "reboot-wtmp" subtest fails because it it assumes that there is a
reboot record even on the initial boot. This is only the case if wtmp is
created within the activation script, but the implementation now uses
tmpfiles.d, so the creation of the file is done at a much later stage.

Apart from that, if you think about the state after the installation as
"first boot", using the term "reboot" wouldn't probably make sense
either.

So in our subtest, we now reboot the machine and check the wtmp record
afterwards as we did before.
