[ASan] Refactoring: nuke the redundant function declarations in asan_intercepted_functions.h

that had been used on OS X only.
The INTERCEPTOR() macro on OS X is now responsible for declaring the wrapped function, the wrapper and the
pair of pointers to them in __DATA,__interposition section. Thus adding an interceptor requires editing a single file now.
