[Buildroot] [git commit] utils/getdeveloperlib.py: print warnings/errors to stderr

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=83f82bd67a2f2e389584586a7016b3e7f85cff37
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Instead of stdout where it gets mixed with the normal output, confusing
software parsing the output (E.G. get-developers -e as git sendemail.ccCmd).
