KUDU-1377: Ignore corrupted trailing records on LBM metadata

This causes the LogBlockManager to tolerate trailing truncated records
in container metadata files. This can occur in a crash or full-disk
scenario.

Adds a test that corrupts a LBC metadata file in various ways.

Also makes ScopedCleanup cancelable.
