[Tarantool-patches] [PATCH luajit v2 1/2] ci: add arm64 architecture to exotic testing

[Sergey Kaplun via Tarantool-patches <tarantool-patches@dev.tarantool.org>]

This commit adds the matrix column with CPU architecture dependency to
be used in future workflows. However, the dual-number mode is default
for arm64 in LuaJIT, so its excluded from the matrix.
