x11/gxkb: the port had been updated to the latest version 0.9.5

This release comes with 65 new country flags; others had been redrawn
in a new style (borderless with rounded corners). Unfortunately, two
flags we pull from the earlier version adhere to the previous style
and thus do not quite fit. This is acceptable for now, but we should
really replace them with better matching versions obtained elsewhere.
