rcutorture: Add --bootargs parameter to kvm-again.sh

Browse source

The kvm-again.sh script can be used to repeat short boot-time tests,
but the kernel boot arguments cannot be changed.  This means that every
change in kernel boot arguments currently necessitates a kernel build,
which greatly increases the duration of kernel-boot testing.

This commit therefore adds a --bootargs parameter to kvm-again.sh,
which allows a given kernel to be repeatedly booted, but overriding
old and adding new kernel boot parameters.  This allows an old kernel
to be booted with new kernel boot parameters, avoiding the overhead of
rebuilding the kernel under test.
