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.
Fixes: 9b07e27f88b9 ("perf inject: Add jitdump mmap injection support")
