selftests/bpf: Remove redundant config option from selftests fragments

CONFIG_IPV6_SEG6_LWTUNNEL is currently enabled in each arch-specific
config fragment for the BPF selftests. Commit 33a971d549d8
("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.
