[PATCH] ui/gtk: Strip trailing '\n' from error string arguments

[Philippe Mathieu-Daudé]

error_report() strings should not include trailing newlines.

Noticed running:

  $ spatch \
    --macro-file scripts/cocci-macro-file.h \
    --sp-file scripts/coccinelle/err-bad-newline.cocci \
    --keep-comments --use-gitgrep --dir .
  ./ui/gtk.c:1094:56:"gtk: unexpected touch event type\n"

Fixes: 5a4cb61ae1 ("ui/gtk: enable backend to send multi-touch events")
