Subject: [PATCH] travis: print cppcheck's output to stdout

This prevents Travis from believing that an error has occurred after
10 minutes without output. Capture error messages in a file and print
its content after cppcheck has finished.

Exit the script with cppcheck's exit code.

Thanks @turol for your help with this!
