CryptoPkg SysCall Lib: Fix warning with GCC in CrtWrapper.c
Exit is declared to be 'noreturn' function, but GCC sees that the empty function will return. Therefore, GCC flags a warning. To work-around this, we use a function pointer, along with a cast to force the code to think that a 'noreturn' function is being called.
