rhui(alibaba): add ARM RHEL8 and RHEL9 setup entries (oamg#1277)

Since leapp's RHUI mechanism filters setups based on the architecture of the source system,
it was not possible to upgrade of ARM-based RHEL systems on Alibaba cloud as there
were no ARM entries in RHUI_SETUPS. This patch adds these entries, making it possible
for EL 8 -> 9 upgrades of ARM systems on Alibaba cloud.
