terminal: fix encoding of mouse buttons 6 and 7 in mouse events

These two buttons were encoded using the *exact* same numbers as
button 4 and 5 (scroll wheel up/down), making it impossible to
distinguish them.

The relevant section from XTerm’s control sequences documentation is:

    Some wheel mice can send additional button events, e.g., by tilting the
    scroll wheel left and right.

    Additional buttons are encoded like the wheel mice,

    o  by adding 64 (for buttons 6 and 7), or

    o  by adding 128 (for buttons 8 through 11).
