Fix #3787: only inhibit some hooks for org-src ops

Inhibiting all MAJOR-MODE-hook functions (to fix #3660) would mean
inhibiting some useful functionality, like indentation or syntax
highlighting modes. We only want to inhibit expensive hooks. Since Doom
adds these to MAJOR-MODE-local-vars-hook by convention, we can
selectively inhibit those instead.
