lib: move DEP0023 to end of life

This commit moves DEP0023 to end of life status. The
os.getNetworkInterfaces() method was introduced in the
unstable 0.5.0 release, and runtime deprecated in 0.6.0, the
first stable release of its existence.

This commit also fixes an inaccuracy in the deprecation, as the
replacement (os.networkInterfaces()) is actually a method.
