Avoid suppressing -Wcast-function-type warning.

GCC special-cases the type ‘void (*)(void)’ to not emit warnings when
cast, see
https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html#index-Wcast-function-type.
Make use of this to remove a warning suppression.

* src/dynlib.h: Use void (*)(void) as generic function pointer type.

* src/emacs-module.c: Remove warning suppression.
