profiling: Pass the TLS certificate to jeprof

[Connor1996]

Fix #1613

Fix it by passing the TLS certificate to jeprof.

By the way, fix some potential issues in jeprof:

• Join the port to jeprof temporarily file name, otherwise multiple instances deployed in the same host may write to same temp file
• Clean up collected profile files when finished instead of keeping them
