ref-filter: add support for %(upstream:track,nobracket)

Browse Source 
Add support for %(upstream:track,nobracket) which will print the
tracking information without the brackets (i.e. "ahead N, behind M").
This is needed when we port branch.c to use ref-filter's printing APIs.

Add test and documentation for the same.
