perf hists: Add color overhead for stdio output buffer
Following commit tightened up the buffer size for output to strict width
of used format columns:
99cf666 perf hists: Fix formatting of long symbol names
This works fine until you hit color overhead output which places extra
bytes into output buffer. We need to account for color overhead in the
output buffer. Adding maximum color byte size to the output buffer size.
