Пакет rpm-build-python: Информация

- Cherry-picked some improvements:
  [0.36.8-alt1] (Minor backports from rpm-build-python3.)
  + .prov.py: generalize to generate longer provs, too.
  + %python_req_nohier added, the reverse to %python_req_hier
    (in future, when there is enough provs, we'd like to
    use the req_hier mode by default; packages can prepare beforehand)
  + Print a bit more diagnostics for ignored/skipped/hidden autoreqs.
  [0.36.7-alt1]
  + %python{,_build}_install: force deterministic behavior (useful in
  case of conflicting stuff from simultaneous python2 and python3 builds).
  + compileall.py: depth-first processing (like in rpm-build-python3).
  [0.36.5-alt1]
  + python.compileall.py: remove unused variable;
  + brp-bytecompile_python: remove unused file (packaged in rpm-build).

- python.compileall.py:
  + removed python version <= 2.2 py_compile workaround;
  + fixed file executability check (by iv@).
- python.{prov,req}.files:
  + enhanced "python script text executable" type check;
  + added is_python3_path check from python.{prov,req}.py,
    which is now applied only to files of uncertain type.
- python.{prov,req}.py: removed is_python3 check.
- brp-bytecompile_python:
  added $RPM_PYTHON3_COMPILE_INCLUDE to the exclude list (closes: #28606).

- python.{prov,req}.files: reintroduced optimization from 0.36.0-alt3.
- python.prov.files: skip all files that cannot be provided due to
  rpmbuild restrictions.
