Subject: selftests/bpf: Add helpers for getting socket family & type name
Patch-mainline: v5.6-rc1
Git-commit: a9ce4cf4e47c55ab40641b92551bc9e1de4bfa61
References: bsc#1177028
Having string arrays to map socket family & type to a name prevents us from
unrolling the test runner loop in the subsequent patch. Introduce helpers
that do the same thing.
