Handle .geoipupdate lock file

Summary:
The geoipupdate client creates a lockfile to avoid race conditions.

Drawbacks of the current method is:

• no lock file created at first run
• can be confusing to see it afterwards

To address both those concerns, the wrapper creates and deletes
this lock file before and after the container run.
