Subject: [PATCH net-next 1/6] seg6: Fix TLV definitions

The definitions of TLVs in uapi/linux/seg6.h are incorrect and
incomplete. Fix this.

TLV constants are defined for PAD1, PADN, and HMAC (the three defined in
draft-ietf-6man-segment-routing-header-19). The other TLV are unused and
not correct so they are removed.
