bitbake: wget.py: parse only <a> tags 

For two reasons:
1) The important one: we hit the following bug when doing upstream version checks
on some webpages:
https://bugs.launchpad.net/beautifulsoup/+bug/1471755

2) Also, documentation for beautifulsoup states that memory usage and
speed is improved that way.

(Bitbake rev: 7546d4aeb3ba8fda9832081b84d93138dc5e58d6)
