fa5500228e build-style/python3-{module,pep517}.sh: improve pytest usage
1. Relying on `python3 -m pytest --help` to test for pytest can fail
   because the pytest packages's __main__ is still invoked; this can
   trigger import problems and falsely indicate that pytest is missing.
   A simpler test is to just confirm that pytest is importable. If so,
   the interpreter returns 0. Otherwise, an ImportError is thrown and
   the interpreter will return 1.

2. Many templates require a custom do_check just to set PYTHONPATH to
   either a build directory (especially for compiled extensions) or some
   subdirectory of the source tree. Setting PYTHONPATH automatically to
   the build directory should drastically reduce the need for custom
   do_check in py3 templates. (This only applies to python3-module.sh
   because pep517 builders will have unpredictable build directories.)

Closes: #31354.

74e0a12915 build-style/python3-pep517: make sure ./build exists in do_install
This allows templates to override do_build and not have to create the
build subdirectory used as TMPDIR in do_install; failure to create this
directory will cause pip to use (and pollute) /tmp in the masterdir.
