    tzcode: Tweak open flags.
    
    Upstream uses a set of flags that reduces to O_RDONLY | O_CLOEXEC when
    you ignore flags that either don't exist in FreeBSD or have no effect.
    We were using O_RDONLY | O_BINARY, which reduces to O_RDONLY.  Add
    O_CLOEXEC.  Also replace O_RDONLY with the more accurate O_SEARCH when
    opening TZDIR.
    
    MFC after:      3 days
    Fixes:          967a49a21a27 ("Update tzcode to 2025b")
