[RFC PATCH v4 0/2] perf/kselftest: convert Perl test helpers to Python

[Breno Rodrigues Alves]

This is v4 of the series converting the Perl test helpers to Python.

Changes since v3:
 - Fixed pylint W1514 in check_errors_whitelisted.py by passing an
   explicit encoding to open():
     open(path, encoding="utf-8", errors="surrogateescape")
   "surrogateescape" preserves the byte-for-byte behavior of the Perl
   original, which reads raw bytes.

 - Also fixed two issues found while testing the series locally:
   * open() failures on the whitelist now exit with the underlying
     errno (matching Perl's die), e.g. ENOENT -> rc 2, instead of
     always rc 1.
   * stdin/stdout are reconfigured with surrogateescape so that
     non-UTF-8 bytes in the log (e.g. oops/KASAN output) do not
     raise UnicodeDecodeError/UnicodeEncodeError, preserving the
     byte-for-byte behavior of the Perl originals.

 - The series is split by tree, addressing Ian's suggestion:
   * Patch 1 (kselftest:) touches only tools/testing/selftests/ and can
     go through the kselftest tree.
   * Patch 2 (perf/tests:) touches only tools/perf/ and can go through
     the perf tree.

 - Note on pylint-tests: it fails on tools/perf/tests/shell/lib/
   perf_json_output_lint.py with:
     W4904: Using deprecated class FileType of module argparse
   This is pre-existing in perf-tools-next and reproduces on the base
   commit without this series. The four files touched by this series
   pass pylint 10/10 with the flags used by Makefile.perf.
