FileSnapshot: silence "Not a Directory" exceptions

Sometimes a FileSystemException with "Not a Directory" can be thrown
while creating a FileSnapshot, likely because the file or directory was
deleted. Since NoSuchFileExceptions are already silenced, and the
FileSnapshot already handles all IOExceptions, there is likely no value
in seeing this info in the logs, treat these situation the same and
silence them also.
