perf: replace strcpy() with strncpy() in util/jitdump.c

Browse source

Usage of strcpy() can lead to buffer overflows. Therefore, it has been
replaced with strncpy(). The output file path is provided as a parameter
and might be restricted by command-line by default. But this defensive
patch will prevent any potential overflow, making the code more robust
against future changes in input handling.

Testing:
- ran perf test from tools/perf and did not observe any regression with
  the earlier code
