glog: Fix coloring when scrolling

Due to the formatting placeholders sitting on the previous line, the
coloring of the topmost line disappeared when scrolling (as the escape
sequence scrolled away). This had the background that I wanted the code
that sets up the format string to be very readable and if possible very
close to the actual output. And since the colors have all different
lengths I decided to place them on the previous line to have them out of
the way.

Fix this by placing the placeholders on the same output line while still
maintaining a readable format string (code). This is done by joining the
array without placing newlines so that it can now have multiple elements
for one output line and formatting those as wished.
