kjellander@webrtc.org f08f52f136 Fixing issues with slaves.cfg on Windows.
This fix is needed for our own build slaves to work properly on Windows and is caused by the hacky way we created the Libvpx waterfall to avoid duplicating unnecessary Python code.

BUG=None
TEST=Tested on Windows build slave.

Performs changes after checkout needed for WebRTC buildbot customizations.
This script performs the following tasks:
- Adds an import of the WebRTC slave_utils module in the buildbot.tac file.
It will add a comment and the import at the end of the file, if it's not
already present.
- Removes the slaves.cfg for the Libvpx waterfall on Windows platforms, since
symbolic links are not available on this platform and the resulting link
file causes a parsing error in Python when loaded during slave startup.
Using this script, we don't need to maintain our own version of the slave
scripts and can automatically stay up to date with their changes.
This script should be invoked as a hooks step in the DEPS file, like this:
hooks = [
{
# Update slave buildbot.tac to include WebRTC slave_utils import.
"pattern": ".",
"action": ["python", "tools/fix_webrtc_buildbots.py"],
},
]
