Time out and dump stacks from R8 processes after 30 minutes

Browse Source 
R8 processes are sometimes hanging on the build servers.  Wrap R8 with
run_with_timeout to dump the stacks with jstack and kill the process
after 30 minutes.  Switch from running with the r8-compat-proguard
shell script to running the jar directly so that jstack gets the pid
of the java process.
