Auto merge of #2530 - de-vri-es:tty-cleanup, r=JohnTitor

Move more ioctl constants and flags to linux::arch::* modules.

This PR moves a few things to `linux::arch::*` modules and out of libc specific modules. Specifically, it:
* Moves the `TIOCM*` ioclt constants and associated flags.
* Moves the `BOTHER` flag.
* Adds the `IBSHIFT` flag.

Without this PR, there are some arch+libc combinations that are missing some of these constants. Since these are all ioctl numbers or arguments to ioctls, they are not specific to any libc flavour. `BOTHER` and `IBSHIFT` don't even appear in glibc or musl headers.
