In 7af137b72131 ("selftests: net: Introduce first PMTU test") I
accidentally assumed route_get_* helpers would run from a single
namespace. Make them a bit more generic, by passing the
namespace command prefix as a parameter instead.

David suggests it's more intuitive to return non-zero on
failures, and zero on success.
No need to introduce tail 'return 0' in functions, they will
return the exit code of the last command anyway.

One single test implemented so far: test_pmtu_vti6_exception
checks that the PMTU of a route exception, caused by a tunnel
exceeding the link layer MTU, is affected by administrative
changes of the tunnel MTU. Creation of the route exception is
checked too.
