sys: fix skipping of syscalls with unknown constants
...
Still need to generate description for such syscalls so that
they at least can be parsed, and so that Go and C entries match.

overhaul syscall description generation process
...
This splits generation process into two phases:
1. Extract values of constants from linux kernel sources.
2. Generate Go code.
Constant values are checked in.
The advantage is that the second phase is now completely independent
from linux source files, kernel version, presence of headers for
particular drivers, etc. This allows to change what Go code we generate
any time without access to all kernel headers (which in future won't be
limited to only upstream headers).
Constant extraction process does require proper kernel sources,
but this can be done only once by the person who added the driver
and has access to the required sources. Then the constant values
are checked in for others to use.
Consant extraction process is per-file/per-arch. That is,
if I am adding a driver that is not present upstream and that
works only on a single arch, I will check in constants only for
that driver and for that arch.

sys: change int range to use ':' instead of '~'

We can't use '-' because '-' can denote negative numbers.
Colon is used is several range notations (e.g. Go, Mathlab, Excel).

sys/sysgen/prog: support ranged int
...
This commit supports inclusive ranged int, like foo int32[-10~10], which will
generate random integer between -10 and 10. In future we will support more than
one range, like int32[0, -5~10, 50, 100~200]

This is not fully working now: e.g. prog and sys packages assume
that pointer size is 8. But at least it compiles and works.

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)
