Compliance: Forward multiple unknown HTTP Cache-Control directives.

httpHdrCcParseInit() ignored all unknown Cache-Control directives
except for the first one because the (type != CC_OTHER) check
applied to the debugging statement only.

Co-Advisor test case: test_case/rfc2616/endHdr-fwd-set-Cache-Control-toSrv
