volume: Show overamplified icon when in overdrive

Show an overamplified volume icon if volume is louder the max normalized one.
Use a similar logic as gnome-settings-daemon to delimit values, restricted
to output.
The purpose is to help users remember that visiting some websites or
using some apps can get LOUD.
