    test/bioprinttest.c: skip failing checks on HPE NonStop

    Apparently, NonStop libc's printf implementation is not
    standard-conforming in its handling of "0" flag with "o" specifier:
    per [1], "it shall increase the precision, if and only if necessary,
    to force the first digit of the result to be a zero", however, NonStop
    libc adds a superfluous zero in cases where precision is 1;  see also
    commit 0f107c709c73 "crypto/bio/bio_print.c: avoid superfluous zero
    padding in %#o".  Avoid test case failures by wrapping the relevant test
    cases in "if !defined(__TANDEM)".
