When packaging YNL as a system level utility we added a --family
argument which auto-resolves the full spec path from a well known
path in /usr/share. Spelling out full YAML spec files is at this
point only done in-tree, for example in the selftests which need
the very latest YAML. But the selftests have their own wrapping
classes for each family so test authors aren't really bothered
by having to spell the paths out.

Afford the same ease of use to the Python library users.
Move the path resolution from the CLI code to the library.
This simplifies the pyynl use by a lot:

  from pyynl import YnlFamily

  ynl = YnlFamily(family="netdev")

Unless I'm missing a trick, resolving the /usr/share path
is hard enough for most users to lean towards shelling out
to ynl CLI with --output-json, which is sad.

 - fix the ethtool script (Donald)
 - fix --family=X --validate (Clashiko)
