Nicolas Hillegeer 522a15f1c0 test: fix formatc.lua oddity on OSX/gcc ...

The primitive C canonicalizer we use to strip out duplicate header
declarations and keep luajit's ffi happy, didn't work properly in this case.

What happened is this (in /usr/include/ctype.h):

__DARWIN_CTYPE_TOP_inline int
isspecial(int _c)
{
        return (__istype(_c, _CTYPE_T));
}

Gets preprocessed to something like:

__inline int
isspecial(int _c)
{
        return (__istype(_c, _CTYPE_T));
}

On OSX/gcc. The formatter wasn't recognizing this entire function as
something to put on a single line because it naively just checks for
"static" or "inline" for that, but not "__inline".

This error doesn't occur on OSX/clang. Without looking further into it, I
guess that __DARWIN_CTYPE_TOP_inline gets defined to inline on clang, but
__inline on gcc, for some reason.

This helps issue #1572 along.
