Fix fontification of keywords clobbered by the prompt.

* lisp/comint.el (comint-output-filter): Remove the uses of
with-silent-modifications I introduced as part of the last change.

This fixes, e.g., erratically missing highlighting when running
./configure --help; ./configure in a shell-mode buffer with
compilation-shell-minor-mode turned on.
