Fix doom-guess-mode-h being too aggressive

Browse source 
It would trigger set-auto-mode whenever files are written to (e.g. when
persp-mode writes its workspace/session files, which have unsafe local
variables, so the user is inundated with prompts to accept them).

Now, doom-guess-mode-h will only work on files with shebang lines.
