  Reland "[Sanitizers] Intercept timer_create" (#113710) (#116717)

Original commit 2ec5c69b6872b8b474f3d37b9125d3d57d144d1b only
intercepted timer_create.

Because of how versioned libc symbols work, this could cause problems
where a newer `timer_create`
was used, and the result would be used by an older version. This would
cause crashes. This is why we
need to intercept all of the related functions.
