var: allow GIT_EDITOR to return null
The handling to die early when there is no EDITOR is valuable when used in normal code (i.e., editor.c). In git-var, where null/empty-string is a perfectly valid value to return, it doesn't make as much sense. Remove this handling from `git var GIT_EDITOR` so that it does not fail so noisily when there is no defined editor.
