[Linux-ia64] chatr.c with GPL

It was pointed out to me that I mailed out the (trivial) chatr.c
utility without a license.  To avoid any confusion, I put the GPL
header in it and placed the updated version at:

	ftp://ftp.hpl.hp.com/pub/linux-ia64/chatr-v0.0.tar.gz

Compressed, it's all of 1469 bytes, md5sum:

	299bf94dcdb0f40fa320c83050c5c367  chatr-v0.0.tar.gz
