Input: atakbd - fix Atari CapsLock behaviour

BugLink: https://bugs.launchpad.net/bugs/1801900

[ Upstream commit 52d2c7bf ]

The CapsLock key on Atari keyboards is not a toggle, it does send the
normal make and break scancodes.

Drop the CapsLock toggle handling code, which did cause the CapsLock
key to merely act as a Shift key.
