devtools: skip experimental libraries in ABI check

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.
