Disable SYSRQ support by default for added security

The magic SysRq is meant for development and debugging. Instead of
trying to determine whether it can be used to break into a Linux system,
we decided to pre-emptively steer clear of any potential security
vulnerabilities by disabling it by default.

Developers can re-enable it through sysctl or by using the kernel
command line option sysrq_always_enabled.
