Adjust function definitions in sysv_msg.c to avoid clang 15 warnings

With clang 15, the following -Werror warnings are produced:

    sys/kern/sysv_msg.c:213:8: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
    msginit()
           ^
            void
    sys/kern/sysv_msg.c:316:10: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
    msgunload()
             ^
              void

This is because msginit() and msgunload() are declared with (void)
argument lists, but defined with empty argument lists. Make the
definitions match the declarations.
