update package fixture to module level for iface_loopback_action (#7593)

iface_loopback_action folder was new added in #5871.
It uses package level fixture which will run the conftest before sanity check.
In ports_configuration it did some remove vlan member or portchannel member operation, which will cause the following sanity check failure obviously.

What is the motivation for this PR?
Make sanity check run before conftest of iface loopback action.

How did you do it?
Use module level fixture instead.
