BootReceiver: add ro.boot.bootreason property to SYSTEM_LAST_KMSG

Browse Source 
Instead of requiring the kernel to join last_kmsg and the reboot
reason together, allow both to be passed to userspace and have
userspace combine them the way the log parsers want them.

Existing devices with no ro.boot.bootreason property and kernel
support for putting the reason in last_kmsg will continue to
use the kernel's formatting.
