[Buildroot] [PATCH 1/1] package/luvi: fix build with aarch64

[Fabrice Fontaine]

aarch64 is a supported architecture of luajit since switch to moonjit
fork in commit 2ca0accc21a090874ac6e97670b47153a1f0a0b5 so manage this
new target in luvi.mk to avoid an "unknown architecture" build failure

Fixes:
