    fate/astc: pipe the KTX header and HDR reject outputs

    The header test wrote two KTX files only to read a few header fields,
    the reject test wrote a file it expects to fail. Pipe the header test's
    output into od, which dumps the fields from glInternalFormat to the
    mipmap level count, and send the reject test's output to stdout.
