Call alternate CFHTTPCookie functions if available

Fixes <http://webkit.org/b/52637> <rdar://problem/8878984>.

Reviewed by Darin Adler.

* platform/network/cf/CookieJarCFNet.cpp: Added soft-linking macros to
pull in the alternate CFHTTPCookie functions.

(WebCore::cookieDomain):
(WebCore::cookieExpirationTime):
(WebCore::cookieName):
(WebCore::cookiePath):
(WebCore::cookieValue):
Added these wrappers around the CFHTTPCookie functions. We call the
alternate functions if they exist, otherwise fall back to the current
functions.

(WebCore::filterCookies):
(WebCore::getRawCookies):
(WebCore::deleteCookie):
Changed to use the wrapper functions.
