In ElectroBSD I removed TIOCSTI support in 2017 [0] and haven't
noticed any problems.

According to the commit message "TIOCSTI is still used in tcsh,
but as tcsh isn't compiled on ElectroBSD we don't care".


All of tcsh's uses of TIOCSTI are in `#ifdef TIOCSTI` blocks so tcsh
should still build and function with it removed (e.g., with the ioctl
renamed) I imagine.
