[sonic-bgpcfgd] Call Python 3 version of sonic-cfggen for testing (#5847)

Browse Source 
sonic-bgpcfgd build fails in the absence of Python 2, as it attempts to explicitly call sonic-cfggen using `/usr/bin/python2.7`. Also, it attempts to call sonic-cfggen using a local, relative path. Since the sonic-config-engine package is not installed, neither are its dependencies.

Now, we configure the Python 3 sonic-config-engine as a dependency of sonic-bgpcfgd, which ensures the Python 3 sonic-config-engine package and its dependencies are installed before sonic-bgpcfgd is built/tested.
