libsnapshot: Eliminate per-snapshot flocks.
Per-snapshot locks don't solve any problems and add a great deal of
complexity. Instead, refactor the Read/WriteSnapshotStatus methods so
the caller just needs the snapshot name, and is not responsible for
opening a file.
As part of this change, callers of WriteSnapshotStatus must always take
an exclusive flock on the update state file. This is enforced by adding
a helper method to LockedFile to check the lock mode.
