fsjobqueue: accept jobs of any type

Soon, we want to begin tagging the jobs with the name of its submitter.
The simplest way to add a tag to a job is to put it into its type string.
However, as we don't know (and don't want to know) the submitters' names when
osbuild-composer is initialized, we need to be able to push arbitrary job
types into the jobqueue.

This commit therefore lifts the restriction that a jobqueue accepts only
a predefined set of job types. Now, jobqueue clients can push jobs of
arbitrary names.
