selftests/bpf: Test resolve_btfids arena argument suffixes

Add a suffix-only kfunc declaration with arena annotations on all five
arguments. Verify that resolve_btfids emits address_space(1) type tags
for every position without KF_ARENA_ARG flags in the BTF ID sets.

Represent expected arena arguments as a per-parameter bitmap so the
test covers suffixes beyond the two positions expressible by flags.
