swscale/x86/swscale: Remove superfluous and invalid ';'

Inside a function an unnecessary ';' is just a null statement;
yet outside of it it is actually illegal (but compilers happen
to accept it without warning except when using -pedantic).
So modify the macros to always expect the user to add a ';'.
