312bfbac26 Use -B flag for Python when using compileall2 to not write pyc files
The Python compileall2 module in /usr/lib/rpm/redhat/
can be executed by various different Python interpreters.
We don't want to write several different `*.pyc` files
to this location - in most cases, that's not possible,
but somebody might run this as root.

6335a7ff4a Fix brp-python-bytecompile with the new features from compileall2
Resolves: rhbz#1595265

The problem this change is intended to solve is with how `real_libdir`
is calculated. Let's assume we want to recursively byte-compile all
`*.py` files in
`/builddir/build/BUILDROOT/python-scales-1.0.9-250.fc32.x86_64/usr/lib/python3.8`.
Then, `real_libdir` is this path without `$RPM_BUILD_ROOT` with
the filename at the end which displays in the error message like this:

```
Bytecompiling .py files below /builddir/build/BUILDROOT/python-scales-1.0.9-250.fc32.x86_64/usr/lib/python3.8 using /usr/bin/python3.8
*** Error compiling '/builddir/build/BUILDROOT/python-scales-1.0.9-250.fc32.x86_64/usr/lib/python3.8/site-packages/greplin/bar.py'...
  File "/usr/lib/python3.8/bar.py", line 1
    import sin from math
               ^
SyntaxError: invalid syntax
```

`/usr/lib/python3.8/bar.py` is obviously wrong.

One of the new features of the `compileall2` module (which will
be available in stdlib in Python 3.9) is that the path byte-compiled to
`*.pyc` files is calculated for each file. This means that by using
`-s` and `-p` we can strip `$RPM_BUILD_ROOT` and prepend `/` for each
file individually which will fix the problem.

```

This change has an effect only for Python >= 3.4.
