(perl #126228) partly revert 8cc95fdb and fix a3c8358c

a3c8358c changed:

-#define dXSUB_SYS int dummy
+#define dXSUB_SYS

which made dXSUB_SYS into not-a-declaration, this apparently broke
something, since 8cc95fdb then went through all the definitions of
dXSUB_SYS, made each of them into not-a-declaration and then
ensured ExtUtilis::Miniperl emitted dXSUB_SYS in a place where it
didn't matter whether it was a declaration or a statement.

When these changes were made perl.h didn't have dNOOP, but now we
do, so we can make dXSUB_SYS a declaration again, as its name
implies.

Based on a patch originally created by Daniel Dragan (bulk88).
