rcutorture: Allow Kconfig-related boot parameters to override

Browse source 
As it stands, the default kernel boot parameters generated from
the Kconfig fragment will override any supplied with the .boot
file that can optionally accompany a Kconfig fragment.  Rearrange
ordering to permit the specific .boot arguments to override those
generated by analyzing the Kconfig fragment.
