bug#24494: 24.4; Trailing comma in emacs-module.h

[Christopher Wellons]

Building Emacs itself now requires a C99 compiler, but this requirement
needn't extend to dynamic modules. Removing a trailing comma (see patch)
makes emacs-module.h C89/C90 compatible, allowing modules to be built
using older C compilers. Trailing commas weren't permitted until C99.
