files-backend: remove the use of git_path() 

Given $GIT_DIR and $GIT_COMMON_DIR, files-backend is now in charge of
deciding what goes where (*). The end goal is to pass $GIT_DIR only. A
refs "view" of a linked worktree is a logical ref store that combines
two files backends together.

(*) Not entirely true since strbuf_git_path_submodule() still does path
translation underneath. But that's for another patch.
