Exclude the build directory of swift-xcodegen from Python lint tests

[omochi]

Using swift-xcodegen creates a build directory at utils/swift-xcodegen/.build.

When running test/Python/python_lint.swift, Python files inside the build directory are scanned, resulting in a large number of lint errors being reported.

This patch resolves the issue by specifying an option for the lint command to exclude the .build directory from being scanned.

The lint errors that were occurring are below.
Some parts have been truncated due to GitHub’s limitations.

@hamishknight could you take a look at this patch?

[hamishknight]

We have a .flake8 configuration file in the repo that configures this, could you edit that instead?

[hamishknight]

Thanks! LGTM

[hamishknight]

@swift-ci please smoke test

[omochi]

I overlooked the configuration file. I have fixed it to use this.
