dependencies: bump min aiorpcx, and enforce at runtime

Note that newer aiorpcx started requiring python 3.8, so we cannot use
the latest versions, until we too bump the min python version to 3.8.
We should not do that until debian stable ships python 3.8.
Also, new aiorpcx introduced some API changes which we will need to
adopt, so even if the user locally has recent enough python, we need
old aiorpcx atm.
