linux-cp: add support for table flush if multiple interfaces

Type: improvement

lcp_router_table_flush() is used to remove routes from the given route
table if they are resolved through the given interface with specified
FIB source. Currently, if you need to remove routes from a route table
that are resolved through one of the interfaces from a vector, the
function has to be executed for every interface from the vector. Every
execution walks the route table again.

With this change, lcp_router_table_flush() accepts a vector of
interfaces. Thus, the function can walk a single route table once and
delete routes that resolve through one of the interfaces from the
vector.
