Michael Weiser 56b57bd20f arm64: Disable unhandled signal log messages by default ...

commit 5ee39a71fd upstream.

aarch64 unhandled signal kernel messages are very verbose, suggesting
them to be more of a debugging aid:

sigsegv[33]: unhandled level 2 translation fault (11) at 0x00000000, esr

Disable them by default, so they can be enabled using
/proc/sys/debug/exception-trace.
