ci: Set default value for INITENV_FLAGS
When no default value for INITENV_FLAGS
is set, the ci build for meta layers will fail with the following error message
$ source init-env $INITENV_FLAGS -m $MACHINE -o build
Passing option: -o to meta-update
* Error: 'Module' object has no attribute '_Module__uri'
Setting a value for INITENV_FLAGS
(even an empty string) fixes this.
