Add runtime crash information to sysprops 



- sys.system_server.crash_java
How many times the system server has crashed within
Java layer. sys.system_server.start_count is the time
that system_server has started.

Normally, (start_count - 1 - crash_java) is the count of
native crash or the other native processes triggered
system_server restart.

We expect the start_count is 1, and the crash_java is 0.

$ getprop | grep system_server
[sys.system_server.start_count]: [5]
[sys.system_server.crash_java]: [2]
...
