Fix for good DefaultTrackingFileManager #1800

[martins-avots]

@cstamas Is the usage of FileLockNamedLockFactory correct for DefaultTrackingFileManager#read?

[cstamas]

Yes it is, but observe this: #1800 (comment)

Summary:

• maven2 locked the file itself
• maven3.x continued doing the same to preserve backward compat (so until this point they could co-exist working on same local repo)
• maven3.10, if change to named locks (they do not lock the subject file, they are pure "advisory locking") this breaks

Check out my counter proposal: #1814
