bpf: Move nf_conn extern declarations to filter.h
We're seeing the following new warnings on netdev/build_32bit and
netdev/build_allmodconfig_warn CI jobs:
../net/core/filter.c:8608:1: warning: symbol
'nf_conn_btf_access_lock' was not declared. Should it be static?
../net/core/filter.c:8611:5: warning: symbol 'nfct_bsa' was not
declared. Should it be static?
Fix by ensuring extern declaration is present while compiling filter.o.
Fixes: 864b656f82cc ("bpf: Add support for writing to nf_conn:mark")
