xfrm: move xfrm4_extract_header to common helper
The function only initializes the XFRM CB in the skb.
After previous patch xfrm4_extract_header is only called from
net/xfrm/xfrm_{input,output}.c.
Because of IPV6=m linker errors the ipv6 equivalent
(xfrm6_extract_header) was already placed in xfrm_inout.h because
we can't call functions residing in a module from the core.
So do the same for the ipv4 helper and place it next to the ipv6 one.
