Manual review of base snaps

Update: Now tracking ABI here: https://github.com/solus-project/runtime-snaps/tree/master/abi

Note the symbol files are around 5MB each so won’t open on GitHub viewer, only raw (it has a link)
Right now fixing some last straggler libs (we shouldn’t have abi_used_libs files if all dependencies are satisfied)

Versioning for runtime set to 3.0.0 to derive from Solus versioning
