[Buildroot] [git commit] package/rpm: use external xz library

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=61c3fbd10bee7784d871b84412aa9d488040a4f3
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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.
