[Buildroot] [git commit branch/next] utils/scanpypi: fix flake8 errors

[Arnout Vandecappelle]

commit: https://git.buildroot.net/buildroot/commit/?id=f982f7043419dea2d21ebe20c1b383633a517674
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/next

Commit e43c0509442c746bea305aa2b0a5f7ff5adfd142 introduced two flake8
errors:

utils/scanpypi:300:26: E231 missing whitespace after ','
utils/scanpypi:302:9: F841 local variable 'setup' is assigned to but never used

The first one is easily fixed. The second one needs a little bit of
explanation. Before commit e43c0509, the return value of
imp.load_module() was used to be able to explicitly call the 'setup'
function in it in case the metadata was not populated. Since that
commit, calling that function is no longer needed, since setup.py is
executed in exactly the same way as when it's run from the command line,
so if that doesn't work, it's completely broken anyway. Therefore, we
can simply discard the return value of imp.load_module().
