init.rc: Disable sysrq from the keyboard
Don't allow the accidental triggering of sysrq functionality
from the keyboard. The only expected use of sysrq functionality
is via /proc/sysrq-trigger
Please see https://www.kernel.org/doc/Documentation/sysrq.txt for
additional information on /proc/sys/kernel/sysrq
