Remove the dependency of tools/bot/bot_utils.py on tools/utils.py

Remove the dependency of tools/bot/bot_utils.py on tools/utils.py

This is needed so that the multivm builder can use bot_utils.py without
checking out tools/gyp, which breaks the multivm build.

you can't do this, this is used in many of the other scripts in here, i.e.,
other scripts here will use bot_utils.utils

OK, I only tested this one.  So I'll leave the function in, but not call it in
this file.  All the other files call the function, and do not use
bot_utils.utils directly, fortunately.
