support/scripts/pkg-stats: fix flake8 E402 warning

flake8 complains with:

pkg-stats:38:1: E402 module level import not at top of file

This is due to sys.path.append() being before the import from
getdeveloperlib, but we really need this sys.path.append() to be
before, so let's ignore this flake8 warning.
