lib/webrick: explicitly convert header values to a string

The values of @header are expected to be all strings;
WEBrick::HTTPResponse::[]=(key, val) explicitly converts the second
argument to a string and assigns it to @header hash.
However, there were some points in WEBrick internal code that assigns
non-String to @header. This change fixes the issues.

The values are checked by header_value =~ /\r\n/ in check_header.
The type confusion caused conflict with removal of Object#=~
[Feature #15231].
