tools/syz-check: add description checking utility
syz-check parses vmlinux dwarf, extracts struct descriptions,
compares them with what we have (size, fields, alignment, etc)
and produces .warn files.
This is first raw version, it can be improved in a number of ways.
But it already helped to identify a critical issue #1542
and shows some wrong struct descriptions.
Update #590
