tc-mpls: fix manpage example and help message string
Manpage:
* Remove the extra "and to ip packets" part from command description
to make it more understandable.
* Redirect packets to eth1, instead of eth0, as told in the
description.
Help string:
* "mpls pop" can be followed by a CONTROL keyword.
* "mpls modify" can also set the MPLS_BOS field.
