31ea20ce83 sys: move generate files to separate packages 
Move generated files to gen subdir. This allows to:
1. Rebuild init.go without rebuilding generated code.
2. Excluding generated files from gometalinter checking.
This makes faster and consume less memory.

08a0ef9cb0 Makefile: fix deps 
syz-sysgen depends on prog which depends on pkg/ifuzz.
Currently we concurrently regenerate pkg/ifuzz and build
syz-sysgen, which can cause failures.
Make pkg/ifuzz dependent on syz-sysgen, so that it is
built before we regenerate ifuzz.

6a0382b543 prog: rework validation code 
The current code is total, unstructured mess.
Since we now have 1:1 type -> arg correspondence,
rework validation around args. This makes code
much cleaner and 30% shorter.

afe402d20a prog: make c.Ret optional 
No reason to allocate return value if there is no return type.
c.Ret == nil is the reasonable indication that this is a "void" call.

9ce14f4b01 prog: Fix page fault for syz-stress users. 
In resources.go, haveGettime is False when SyscallMap["clock_gettime"]
is nil.

In this code, there's a branch that's entered only if Gettime is False,
which appends SyscallMap["clock_gettime"] to resourceCtors.  That is, it
appends nil to resourceCtors, then iterates through resourceCtors and
tries to dereference the .Name of each time, in this case, nil.Name.

This was causing a page fault on Fuchsia.

I'm not certain how the "standard" flow is supposed to work, since it
seems like any code that enters the `if cantCreate == "" && !haveGettime`
should fail... but, removing that section causes test failures, so let's
just enforce that SyscallMap["clock_gettime"] is non-nil.

If there's a better way to solve this, I'm open to suggestions.

However if there are lots of them, they need to be seen in log.
