build-setup: Use flock to setup global configs

In case multiple jobs are started simultaneously (e.g. a matrix
configuration project), the setup script will get an error on writing
the config files, e.g. git config --global will fail with:

    error: could not lock config file

Use flock to make sure they are not accessing the file simultaneously.
