Clipboard: Make both selections available and fix inconsistencies

Browse Source 
Previously, C-y pasted the "primary" selection on X11 and the
"clipboard" selection on Wayland. That's inconsistent and confusing,
especially when you're switching back and forth between the two.

This commit does two things:

1.  It makes C-y always paste the "clipboard" selection.
2.  It adds a key bind C-Y to paste the "primary" selection.

I suspect that most bemenu users are on Wayland, so this commit tries to
not break things for them. It does, however, change the behavior on X11.
