SystemUI: fix right hand side gestures on lockscreen all creds to @romanbb

All credit to @romanbb didn't let me change authorship for some reason
two finger quick pulldown was not accounting for being in the keyguard
adn was eating touch events when it shouldn't be.

Also change from 1/3rd to 1/4th, 1/3 feels a bit too large

SystemUI: fix status bar brightness slider eating events

In some cases it would eat the event and not lose focus to the rest of
the system.
