hex 76d5bb6a13 libbpf: Add VMTEST to CI
Extend continuous integration tests by adding testing against various kernel
versions.
The code is based on vmtest CI scripts implemented by osandov@
for drgn [1] with the following modifications:
- The downloadables are stored in Amazon S3 cloud indexed in [2]
- `--setup-cmd` command line option is added to vmtest/run.sh so
  setup commands run on VM boot can be set in e.g. `.travis.yml`
- Travis build matrix [2] is introduced for VM tests so VM tests are
  followed by the existing CI tests. The matrix has `KERNEL` and
  `VMTEST_SETUPCMD` dimensions.
- Minor style fixes.

The vmtest extention code is located in travis-ci/vmtest and contains
`run.sh` and `setup_example.sh`
- `run.sh` is responsible for the vmtest workflow: downloading vmlinux
  and rootfs image from the cloud, fs mounting, syncing libbpf sources
  to the image, setting up scripts run on VM boot, starting VM using
  QEMU.
  `run.sh` covers more use cases than a script for a job run in TravisCI,
  e.g. int can build a kernel w/ `--build` option.

- `setup_example.sh` is an example of a script run in VM which can be
  modified to e.g. run actual libbpf tests. A setup script should have
  executable permission.

To set up a new kernel version for a test:
1) upload vmlinuz.* and vmlinux.*\.zst to Amazon S3 store
located at [4];
2) modify INDEX [2] file.
