[sanitizer_common] Remove reference to obsolete termio ioctls

[andreas-schwab]

The termio ioctls are no longer used after commit 59978b2
("[sanitizer_common] Remove interceptors for deprecated struct termio
(#137403)"), remove them. Fixes this build error:

This certainly solves the immediate problem, but please see my note on #137321, which I still think is a better approach:
