sys: use kernel headers instead of host headers
...
This solves several problems:
- host usually have outdates headers, so previously we need to define missing consts
- host may not have some headers at all
- generation depends on linux distribution and version
- some of the consts cannot be defined at all (e.g. ioctls that use struct arguments)

vm: faster output oops grepping
...
Use manual parsing instead of a regexp.
Regexp takes ~220ms for typical output size. New code takes ~2ms.
Brings manager CPU consumption from ~250% down to ~25%.
