block-mount base-files: Added additional check to pi_include to ensure that a directory used with pi_include actually contains files matching the souring pattern because if not the shell dies due to an empty string in for statement. Added /lib/functions/fsck as an empty dir to block-mount. This combination fixes a warning which generates a lot of bug reports, without panicking the kernel like the last attempt.
