fix(tools): h5rs check says why the library refused a file

Browse Source 
With the header checks merged, the library refuses truncated files and
misaligned chunk-index keys itself, so check reported only "file cannot
be opened" for a truncated file. It now reports the truncation (stored
end of file vs file length) or the library's error, and the misaligned
chunk test accepts the library's refusal of the key.
