selftests/bpf: convert dynptr_fail and map_kptr_fail subtests to generic tester

Convert big chunks of dynptr and map_kptr subtests to use generic
verification_tester. They are switched from using manually maintained
tables of test cases, specifying program name and expected error
verifier message, to btf_decl_tag-based annotations directly on
corresponding BPF programs: __failure to specify that BPF program is
expected to fail verification, and __msg() to specify expected log
message.
