s390: Move hwcaps/platform names out of _rtld_global_ro

Changes to these arrays are often backported to stable releases,
but additions to these arrays shift the offsets of the following
_rltd_global_ro members, thus breaking the GLIBC_PRIVATE ABI.

Obviously, this change is itself an internal ABI break, but at least
it will avoid further ABI breaks going forward.

-/* This information must be kept in sync with the _DL_HWCAP_COUNT and
-   _DL_PLATFORM_COUNT definitions in procinfo.h.
-
-   If anything should be added here check whether the size of each string
-   is still ok with the given array size.
-
-   All the #ifdefs in the definitions are quite irritating but
-   necessary if we want to avoid duplicating the information.  There
-   are three different modes:
-
-   - PROCINFO_DECL is defined.  This means we are only interested in
-     declarations.
-
-   - PROCINFO_DECL is not defined:
-
-     + if SHARED is defined the file is included in an array
-       initializer.  The .element = { ... } syntax is needed.
-
-     + if SHARED is not defined a normal array initialization is
-       needed.
