    nsswitch.conf: Avoid modification after installation

    To implement WITHOUT_NIS, we have a hack in the build which modifies the
    installed nsswitch.conf to remove NIS compat providers and databases.
    This hack operates on the installed nsswitch.conf, which means that the
    installed file size won't match that listed in the metalog.

    One option would be to maintain two copies of nsswitch.conf, one for
    each configuration, but that would result in duplication and I don't see
    a clear way around that.

    Instead, stage a copy of nsswitch.conf in the libc objdir, and modify
    that one before installing, so that the version recorded in the metalog
    matches what actually gets installed.
