[GSOC PATCH 2/2] builtin/prune: stop depending on 'the_repository'

[Ayush Chandekar <ayu.chandekar@gmail.com>]

Refactor builtin/prune.c to remove the dependency on the global
'the_repository'. Replace all the occurrences of 'the_repository' with
repo and thus remove the definition '#define
USE_THE_REPOSITORY_VARIABLE'
