Removes the '-m' option from the nsenter call in the netns.py agent. The option should have been removed by bcfed98, but was missed. This is necessary to allow the network namespace support to work without admin privileges. Signed-off-by: Nick Potenski <nick.potenski@garmin.com>

With these changes, I am now able to setup and use a network namespace in our Labgrid system. I didn't file bug reports for these, but I can do so for tracking if you would like. |

Looks good to me aside from the nit.
Versions of iproute2 older than 6.0.0, such as those shipped with Ubuntu 22, do not support the '-echo' option. Rewrites the labgrid-raw-interface's handle_ns_macvtap() method to no longer rely on echoing back the result of the 'ip link add' command to determine the new interface name.

Description
Fixes several issues encountered when trying to use RawNetworkInterfaceDriver's setup_netns() method.
First, older version of iproute2 do not include the
-echooption. When trying to uselabgrid-raw-interfaceon a exporter running Ubuntu 22, this would lead to failures when trying to create the macvtap.Second, the
