Philippe Guibert 542a0f7518 sharpd: add uSID instruction support to seg6local routes 
Seg6local routes can be installed with uSID instruction.

> ubuntu2204hwe# sharp install seg6local-routes 1006::1 nexthop-seg6local loop1 uN
> ubuntu2204hwe# Ctrl-D

As of today, uA and uN can be displayed with iproute2. The other
instructions are not rejected by the kernel, but are not displayed by
iproute2.
