[patch] use proper color when drawing border of non-toolkit scroll bars

[Andreas Seltenreich]

Hi,

the border of non-toolkit scroll bars seems to ignore attempts to
customize it via the scroll-bar-foreground frame parameter or the
scroll-bar face.  Attached is a trivial patch to fix it, although I'm
not really sure if it qualifies as a bug.

regards,
andreas
