[RFC PATCH v2 0/2] perf: convert Perl test helpers to Python

[Breno Rodrigues Alves <breno3011alves@gmail.com>]

v2 changes since v1:
  - Restructure as 2 commits (prefix.py alone; the 4 check_*.py together,
    since their callers are heavily intermingled)
  - Update runner.sh and kselftest/Makefile to invoke/install prefix.py
  - Update Makefile.perf to install *.py (not just *.sh/*.pl)
  - Update all call sites in base_probe/ and base_report/
  - Remove the 5 original .pl files
  - Add trailing newlines to all 5 files (pylint C0304)
  - Fix the check_all_patterns_found commit message:
    TESTLOG_ERR_MSG_MAX_LINES is only handled by check_all_lines_matched

This series converts five Perl test helpers in tools/ to Python 3,
continuing the Perl-to-Python conversion effort for the kernel's
auxiliary scripts.

Each conversion is a faithful 1:1 port: same CLI, same output,
same exit codes. All use only the Python standard library.

The five scripts are:
  - prefix.pl                      -> prefix.py
  - check_all_patterns_found.pl    -> check_all_patterns_found.py
  - check_no_patterns_found.pl     -> check_no_patterns_found.py
  - check_all_lines_matched.pl     -> check_all_lines_matched.py
  - check_errors_whitelisted.pl    -> check_errors_whitelisted.py

All five were verified byte-for-byte identical to their Perl
counterparts on synthetic inputs.
