perf inject jit: Fix JIT_CODE_MOVE filename
During perf inject --jit, JIT_CODE_MOVE records were injecting MMAP records with an incorrect filename. Specifically it was missing the ".so" suffix. Further the JIT_CODE_LOAD record were silently truncating the jr->load.code_index field to 32 bits before generating the filename. Make both records emit the same filename based on the full 64 bit code_index field.
