[PATCH v2] os/xsha1.c: Add license and copyright attribution.

[Carl Worth]

I'm interested in copying this code to the mesa project, but before
doing that it seems prudent to have the license and copyright
attributions in place before copying that. To get this list of names I
went through:

	git log -- os/xsha1.c
and:
	git log -- render/glyph.c

Oops. That was an impressive lack of attention to detail on my
part. Thanks for the catch, Daniel. Here's the fixed version.
