Remove the old V4L1 v4lgrab.c file

Remove the old V4L1 v4lgrab.c file

[ upstream commit 55fe25b418640fad04190103274841b2c907bacd ]

This example file uses the old V4L1 API. It also doesn't use libv4l.
So, it is completely obsolete. A good example already exists at
v4l-utils (v4l2grab.c):
	http://git.linuxtv.org/v4l-utils.git

[AK: included in 2.6.35 because v4lgrab doesn't build without
the host's linux/videodev.h]
