arch-arm64.inc: don't append _be to ARMPKGARCH for tune-aarch64_be

arch-arm64.inc: don't append _be to ARMPKGARCH for tune-aarch64_be

* the _be suffix is already included in ARMPKGARCH with:
  ARMPKGARCH_tune-aarch64 ?= "aarch64"
  ARMPKGARCH_tune-aarch64_be ?= "aarch64_be"

  and then it was appended again through ARMPKGSFX_ENDIAN_64
  TUNE_PKGARCH_64 = "${ARMPKGARCH}${ARMPKGSFX_ENDIAN_64}"

* broken since:
  commit 08433cc58abf0cf3e42b22d20870a50287cfb8bc
