net: define all SOL_* constants

Ensure that all known SOL_* constants are defined.
Sync the list of known SOL_* constants with linux/socket.h.

* net.c: Provide definitions for all SOL_* constants.
Remove all SOL_* preprocessor conditionals.
(socketlayers): Disconnect from inet_protocols.
* xlat/socketlayers.in: Remove SOL_ICMP, add SOL_ALG and SOL_NFC.
