a0be1d1210 pkg/build: copy image to output dir 
For vmm we need a pre-created image.
So if one is provided in the userspace dir,
copy it to output. This should be enough
to get vmm working.

ff2962ae80 syz-ci: de-hardcode kernel object file names 
We used to have this list in syz-ci and syz-managers.
Now we have kernel object in sys/targets, so use it instead.

58f18e3f60 tools/create-gce-image.sh: disable ftrace_dump_on_oops 
We don't have anything useful there.
But sometimes fuzzer somehow poppulates it with some nonsense,
and then it all dumped in crashes.
Disable it.

6b5120a464 tools/create-gce-image.sh: auto-detect block device type 
Currently we choose block device to use (nbd/loop) based on SYZ_VM_TYPE.
Strictly saying these things are orthogonal.
losetup is broken on Ubuntu. qemu-nbd is broken on Debian.
Try to auto-detect what will work based on uname.

196410e4f5 dashboard/config: re-enable selinux 
Upstream "selinux: fix mounting of cgroup2 under older policies"
commit fixes mounting of cgroup2 under wheezy selinux policy.
So don't disable selinux on start.
Create separate cmdline arguments that enable selinux and apparmor.

95b5c82b28 pkg/build: do not use asan for fuchsia 
If we build fuchsia with asan, syz-executor binary fails to run with:

$ /tmp/syz-executor

Disable asan until we figure out how to fix this.

Use separate target as this is something that can be upstreamed.

375a3e31e1 pkg/build: save kernel config early 
Currently we don't capture kernel config for broken builds
because the config is saved as the last step.
Save it as early as possible.

7c31f7a78d pkg/build: always do clean build for fuchsia 
We frequently see boot errors like:

[00010.201] 02991.03067> pkgsvr: 2018/06/30 23:39:41 system: failed to set system root from blob "ccbadb3901372b1e0fc5275f627f708bf3e5f3acfb0d4268638db0ff75fc7fd4": file does not exist

or:

[00003.691] 01126.01153> devmgr: launchpad /fs/blob/e66739acdd3d8efa3b7c9021e2107cf8431765c0b8eb0a1ec7f7dc7fd305f2f7 (pkgfs) failed: launchpad_vmo_from_file failure: -40

Presumably clean build may help.

This can be useful to keep some additional description of the build.

Define interface that each OS needs to implement.
Add gvisor stub.
