[PATCH] v4l2-apps: fix generation of parse.h

[Andreas Oberritter <obi@xxxxxxxxxxx>]

Hello Mauro,

here's a fix for v4l2-apps/util/Makefile: It uses echo -e, which is not
portable across different shell implementations. I replaced it with
printf. That's a common problem on Ubuntu, where dash is used instead of
bash as the default shell.

Regards,
Andreas
