Rewrite Debug for FileLockEntry
Rewrite Debug for FileLockEntry

This changes the implementation of Debug for the FileLockEntry to be
more explanatory of how the entry actually looks like. It does not only
print the path of the store anymore, but also the location of the Entry.

Printing header and content would be still too much, tho.
