    linuxulator: fix SO_PEERCRED emulation after 1d24638d3e8

    For Linux binaries, sopt->sopt_td may be null.  And there's also no
    need to check it, since struct l_ucred has the same layout on 32-bit
    systems as on 64-bit ones.

    PR:             295333
    Reported by:    Miguel Gomes <miguel.dias.gomes@protonmail.com>
    Fixes:          1d24638d3e8 ("Fix LOCAL_PEERCRED in 32-bit compat mode")
