Remove the bzip2 dependency from Lynx. We were previously linking

against bzlib so the library would be used instead of the bzip2 binary.

We now disable bzip2 detection at the configure level (thanks to sthen@
for the pointers), which prevents accepting bzip2 compressed HTML and
thus avoid spawning processes.

OK tb@, sthen@
