setup: split off $GIT_DIR-set case from setup_git_directory_gently

If $GIT_DIR is set, setup_git_directory_gently does not have
to do any repository discovery at all.  Split off a function
for the validation it still does do, in the hope that this will
make setup_git_directory_gently proper less daunting to read.
