SR-MPLS: fixes and tests
- the FIB path takes a vector of type fib_mpls_label_t not u32 so the untype safe vec_add did not work - write som eSR-MPLS tests - allow an MPLS tunnel to resolve through a SR BSID Change-Id: I2a18b9a9bf43584100ac269c4ebc286c9e3b3ea5 Signed-off-by: Neale Ranns <nranns@cisco.com> (cherry picked from commit 7c922dc404c2c0a2d67d53ca05db1c1ae1598f44)
