Two touch tap defaults to middle button instead of right button click

This usually isn't seen because gnome-settings-daemon overwrites the setting once logged in. However, if g-s-d isn't used or isn't running, the user will be left with the wrong setting.

This is due to a bad change in distro patch 104_always_enable_tapping.patch:

- /* Enable tap if we don't have a phys left button */
- tapButton1 = priv->has_left ? 0 : 1;
- tapButton2 = priv->has_left ? 0 : 3;
- tapButton3 = priv->has_left ? 0 : 2;
+ /* Enable tap */
+ tapButton1 = 1;
+ tapButton2 = 2;
+ tapButton3 = 3;
