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.
