package/rpm: use external xz library

Internal xz backend is statically linked and need a static
libintl library when BR2_NEEDS_GETTEXT_IF_LOCALE is set.
But for a shared only build, there is no static libintl available
in the sysroot.

Use the external xz library provided by Buildroot instead of
using the internal xz backend.
