staticd: Extend static_zebra_release_srv6_sid to release SRv6 uA SIDs

Browse source 
When removing an SRv6 uA SID, staticd should ask SRv6 SID Manager to
release the SID.
Currently, `static_zebra_release_srv6_sid` does not allow to release uA
SIDs.

This commit extends `static_zebra_release_srv6_sid` to allow staticd to
release SRv6 uA SIDs.
