linux/x11: Fix CPU being pinned at 100% in X11 loop (#13458)

This was part of https://github.com/zed-industries/zed/pull/13355 to fix
the problem of XIM events not waking up the loop. Problem is that it
seems to pin a single CPU at 100%.

Luckily, it looks like the change is not necessary anymore after we
refactored the improvements in #13355.

This fixes https://github.com/zed-industries/zed/issues/13409.
