rcutorture: Allow Kconfig-related boot parameters to override
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. Signed-off-by: Paul E.
