filter-branch: always export GIT_DIR if it is set

Currently filter-branch exports GIT_DIR only if it is an
relative path but git-sh-setup might also set GIT_DIR to an
absolute path that is not exported yet.  Additionally export
GIT_WORK_TREE with GIT_DIR to ensure that cwd is used as
working tree even for bare repositories.
