          Some minor fixes to http tests.

LayoutTests:

        * http/conf/httpd.conf: don't define CustomLog and ErrorLog - these are now 
        passed from run-webkit-tests.
        * http/tests/favicon.ico: Added.
        * http/tests/incremental/slow-utf8-text.text: Remove an unused variable,
        * http/tests/incremental/split-hex-entities.html: Ditto.
        * http/tests/xmlhttprequest/interactive-state.cgi: Ditto.

WebKitTools:

        * Scripts/run-webkit-tests: Pass CustomLog and ErrorLog directives to httpd.
