rcutorture: Add atomic-SRCU support to torture.sh

Add the --do-atomic-srcu argument to torture.sh, which runs the
SRCU-N, SRCU-P, and SRCU-T scenarios, thus covering both Tree SRCU
(SRCU-N and SRCU-P) and Tiny SRCU (SRCU-T), with
rcutorture.reader_flavor=0x10 appended to the boot parameters so
that it takes precedence over each scenario's own reader-flavor
setting.  This exercises srcu_read_lock_atomic(),
srcu_read_unlock_atomic(), and synchronize_srcu_atomic().

As with other torture.sh tests, the --do-kcsan argument runs a
KCSAN+PROVE_LOCKING variant of this test.
