posix_spawn: fix stack setup on ia64 [BZ #21275]
The ia64-specific clone2 call expects the base of the stack mapping and
the stack size as sep arguments, not an initial stack value as on other
stack-grows-down architectures. Reuse the stack-grows-up macro so we
pass in the right stack base.

+ * sysdeps/unix/sysv/linux/spawni.c [__ia64__] (CLONE): Rename
+ __stack to __stackbase.
+ (STACK): Invert _STACK_GROWS_DOWN and _STACK_GROWS_UP order of
+ checks so we can include defined(__ia64__) first.
