gitk: use text labels for next/prev search buttons

gitk allows searching for commits with various criteria, and provides
up/down search buttons to facilitate this search. These buttons are
labelled with bitmaps, and those bitmaps are not always recolored
correctly for the ui scheme as the theme colors are not known. Let's
just use text labels on these, allowing the styles to handle any
coloring needed. Use utf codepoints for the arrows, presuming that these
code points are available in the selected font.
