    nscd: Use time_t for return type of addgetnetgrentX
    
    Using int may give false results for future dates (timeouts after the
    year 2028).
    
    Fixes commit 04a21e050d64a1193a6daab872bca2528bda44b ("CVE-2024-33601,
    CVE-2024-33602: nscd: netgroup: Use two buffers in addgetnetgrentX
    (bug 31680)").
