Remove --max-{execution, child-process}-seconds

Moving odrefresh into the VM has a nice side effect: Input files are now
cached by the VFS in the VM. Whereas in the previous setup, each dex2oat
has a completely new authfs instance, i.e. same input files need to be
copied for many times.

Currently, odrefresh takes about ~250 seconds to complete, which is
within the time limit. In fact, we've stopped giving the VM extra time
since the migration was done. This change removes the dead flag/code.
