drivers/net/tulip: update first comment in tulip files

Three basic changes to the comments at the top of each file:
1) remove stale "Maintained by" line...I prefer people look in MAINTAINERS.
2) Drop reference to stale sf.net/tulip website (I didn't see anything
   of value there)
3) Point people at bugzilla.kernel.org to submit bugs...will always
   get tracked regardless of who the maintainer is.
