evdev: Don't oveflow when translating buttons to masks

An array is used to translate the button to its mask. Clutter defines
the masks for button 1 to 5 but we report BTN_LEFT..BTN_TASK ie
0x110..0x117. We need to pad the array for the translation not to access
random data for buttons between 0x115 and 0x117.
