    linux_file.c: Fix handling of NFS getdents() emulation

    Bugzilla PR#292282 reports a problem, where a Linux
    binary running in the Linuxulator gets bogus entries
    in a readdir()/getdents() reply when the directory is
    an NFS mount.

    This appears to be caused by the NFS client including
    entries with d_fileno == 0, which are always ignored by
    BSD, but are not ignored by Linux.

    This patch filters out the "d_fileno == 0" entries and
    the reporter of the bugzilla PR notes that it fixes the
    problem for him.

    It could be argued that the NFS client should filter out
    the "d_fileno == 0" entries, but the NFS client readdir
    code is "fragile" and any change to it runs a significant
    risk of causing regression type problems.

    As such, since the LInuxulator is already broken for this
    case, it seems safer to filter them out there.

    PR:     292282

    (cherry picked from commit 110f2567cb51f1eeddbd5d9937000ad64f6dc746)
