[DRE-maint] Bug#996294: Change in webrick 1.7.0 is causing a problem with the tests in Ruby 2.7 (at least)

[Daniel Leidert]

I did some debugging on the issue reported that the tests fail after adding
ruby-webrick 1.7.0 to b-d for Ruby 3.0.

The problem is in parse_header() (lib/httpclient/session.rb) in the line

828             line = socket.gets("\n")

With webrick 1.7.0 it stalls here. This is caused by this small change in
webrick:

https://github.com/ruby/webrick/commit/069e9b1908aad3a30a0dcf67b6d3bb13c3216d2c

If I revert this, the tests no longer timeout and succeed under Ruby 2.7.

Regards, Daniel
