Two minor changes to the kselftest-merge target:
1. Let builtin have presedence over modules when merging configs
2. Merge per-arch configs, if available

The kselftest-merge target walks all kselftests configs, and merges
them. However, builtin does not have precedence over modules. This
breaks some of the tests, e.g.:
$ grep CONFIG_NF_NAT tools/testing/selftests/{bpf,net}/config
tools/testing/selftests/bpf/config:CONFIG_NF_NAT=y
tools/testing/selftests/net/config:CONFIG_NF_NAT=m
Here, the net config will set NF_NAT to module, which makes it clunky
to run the BPF tests.
Add '-y' to scripts/kconfig/merge_config.sh.

Some kselftests has a per-arch config,
e.g. tools/testing/selftests/bpf/config.s390x.
Make sure these configs are picked up by the kselftest-merge target.
