CONFIG_IPV6_SEG6_LWTUNNEL is currently enabled in each arch-specific
config fragment for the BPF selftests. Commit 33a971d549
("selftests/bpf: Add LWT encap tests for skb metadata") has enabled this
config in the generic config as well, resulting in a small warning when
configuring a kernel for selftests:
$ cat tools/testing/selftests/bpf/{config,config.vm,config.x86_64}>.config
$ make olddefconfig
HOSTCC scripts/kconfig/conf.o
HOSTCC scripts/kconfig/confdata.o
HOSTLD scripts/kconfig/conf
config:269:warning: override: reassigning to symbol IPV6_SEG6_LWTUNNEL
#
# configuration written to .config
#
Now that IPV6_SEG6_LWTUNNEL is set in the general config fragment, drop
it from the arch-specific fragments.

`config.{arch}` had entries already present in `config`.
When generating the config used by vmtest, concatenate the `config` file
with the `config.{arch}` one, making those entries duplicated, so remove
those duplications.
Use the following command to get the differences:
$ comm -1 -2 <(sort tools/testing/selftests/bpf/config.x86_64) <(sort tools/testing/selftests/bpf/config)
$ comm -1 -2 <(sort tools/testing/selftests/bpf/config.aarch64) <(sort tools/testing/selftests/bpf/config)
$ comm -1 -2 <(sort tools/testing/selftests/bpf/config.riscv64) <(sort tools/testing/selftests/bpf/config)
$ comm -1 -2 <(sort tools/testing/selftests/bpf/config.ppc64el) <(sort tools/testing/selftests/bpf/config)
$ comm -1 -2 <(sort tools/testing/selftests/bpf/config.s390x) <(sort tools/testing/selftests/bpf/config)
This is similar with commit 7a42af4b94 ("selftests/bpf: Remove entries
from config.s390x already present in config").
