devtools: skip experimental libraries in ABI check

  We don't provide ABI compatibility for experimental libraries.
Skip those libraries by catching a soname containing a version starting
with '0.'.

Align the special case for the glue libraries by using the soname too.
Once libabigail has support for it, we will have a single type of rule.

Fixes: 777014e56d07 ("devtools: add ABI checks")

I am not familiar with the script and how libabigail works, but +1 to the idea.
