[RFC PATCH net-next 08/10] selftests: forwarding: ethtool: Move different_speeds_get() to ethtool_lib

[Amit Cohen <amitc@mellanox.com>]

Currently different_speeds_get() is used only by ethtool.sh tests.
The function can be useful for another tests that check ethtool
configurations.

Move the function to ethtool_lib in order to allow other tests to use
it.
