net: Use 16bits for *_headers fields of struct skbuff
In order to mitigate ongoing incresase in the size of struct skbuff use 16 bit integer offsets rather than pointers for inner_*_headers. This appears to reduce the size of struct skbuff from 0xd0 to 0xc0 bytes on x86_64 with the following all unset.
