Subject: selftests: devlink: Export functions to devlink library
Patch-mainline: v5.5-rc1
Git-commit: 6b45fe95fdbed9950c58186af7940cfed67a08c7
References: bsc#1176774

l2_drops_test() is used to check that drop traps are functioning as
intended. Currently it is only used in the layer 2 test, but it is also
useful for the layer 3 test introduced in the subsequent patch.

l2_drops_cleanup() is used to clean configurations and kill mausezahn
proccess.

Export the functions to the common devlink library to allow it to be
re-used by future tests.
