Use the standard CC_LIKELY and CC_UNLIKELY macros

Several source files privately defined macros LIKELY and UNLIKELY in terms
of __builtin_expect. But <cutils/compiler.h> already has CC_LIKELY and
CC_UNLIKELY which are intended for this purpose.  So rename the private
uses to use the standard names.

In addition, AudioFlinger was relying on the macro expanding to extra ( ).
