p1-common: disable JIT

System-wide JIT memory usage is dependent on the number of applications running
and the code footprint of those applications. The JIT establishes a maximum
translated code cache size and touches the pages within it as needed.
JIT costs somewhere between 3M and 6M across a typical running system.
