app_icons: add the kuhylog app and its track-bars glyph

Three rising bars with a plotted point above the tallest: a day-by-day log
that adds up to a trend, which is what the app tracks. Bars are strokes
rather than filled rects so the glyph keeps one stroke weight, and the
168px pitch leaves 96px gaps -- comfortably above MIN_NEGATIVE_SPACE, which
is where these glyphs usually fail.

kuhylog has a Linux desktop target as well as Android, so it is registered
with linux=True and gets the hicolor set.
