[PATCH 0/3] perf build: Fix pylint build failures

[Leo Yan]

Recent changes to perf's Python module, including enabling pylint by
default, exposed build failures in our CI. For example:

  tests/shell/lib/perf_brstack_max.py:8:0: E0401: Unable to import 'perf' (import-error)

This series ensures the perf Python extension is built before running
pylint on its consumers and prepends the output Python directory to
PYTHONPATH for out-of-tree builds.

The series also mutes the optparse deprecation warning from older pylint
versions. Python has reversed this deprecation, and newer pylint
versions no longer report it.
