[PATCH v4 15/16] osstest: introduce a script to create a FreeBSD flight

[Roger Pau Monne <roger.pau@citrix.com>]

The logic to create a FreeBSD build job is added to
make-freebsd-flight. This includes creating a FreeBSD build job, and
also testing the output of that build job (by creating another build
job that depends on the output of the first).

Note that the FreeBSD build job needs some input in order to setup a
FreeBSD host, and that can be fetched from different places:

1. Env variable FREEBSD_BUILDJOB: use the output from a previous
build-<arch>-freebsd.

2. Env variables FREEBSD_DIST and FREEBSD_VERSION: set before calling
into make-flight, provide the path to the installer image and sets
folder and the version being installed.

3. Config file FreeBSDDist and FreeBSDVersion: same as 2. except that
they are set on the config file.

Changes since v3:
 - Split the sg-run-job code into pre-patches.

Changes since v1:
 - Replace freebsd_buildjob with freebsdbuildjob.
 - Replace FREEBSD_SETS/IMAGE with a single FREEBSD_DIST that points
   to a folder that should contain both things.
 - Document the FreeBSDDist and FreeBSDVersion config file options in
   the README file.

+FreeBSDDist
+   Path to the folder that contains the FreeBSD install image and
