sxhkd: Switch to rofi-pass and pavolume invocation

Switched sxhkd shortcut from rofi-gopass to new rofi-pass
implementation.

Additionally switched from pulsemixer to pavolume for media key volume
control. Pulsemixer works well as a tui application, but its cli
implementation is unbearably slow (on my setup at the very least).

After pressing the volume up/down/mute key it could take up to 3 seconds
to take effect. With pavolume this change happens almost
instantaneously, and it displays a libnotify message on top (can be
disabled).
