Detect system-wide safe mode and configure the VM accordingly.

For the system server process, do the disableJitCompilation/startJitCompilation
callbacks depending on whether the system is in safe mode or not.

In addition, if the system is found to be in safe mode, a flag will be set in
the Zygote class which will be used to launch subsequent apps in VM safe mode.
