osbuild currently throws an error when not passing a build environment
on the command line, because the runner is unset. This is annoying on
hosts which only need a runner set, but no build pipeline.
To simplify running osbuild in this common case, introduce
`org.osbuild.host`, which is a runner that is defined to work on the
host that osbuild is installed on. Use this runner by default and
include a symlink to the right runner in the Fedora and RHEL packages.
Also add `runners/org.osbuild.host` to `.gitignore`, so that developers
can set the symlink when running osbuild from the source directory.
Fixes#171
RPM packages are now kept in output directory after build so that we
know exactly which packages to copy to the test. The test directory now
contains special directory for RPMs. Fedora developer portal is
referenced from README file.
The repository now contains a Vagrantfile for running the testing script
against an RPM package created locally using `make rpm`. To run this
test use `make vagrant-test`. setup.py was also modified to adhere to
packaging guidelines and not to install system-level executables.
The lincense is now included in the Python package using the MANIFEST.in
file.
