    elf: Restore ldconfig libc6 implicit soname logic [BZ #30125]

    While cleaning up old libc version support, the deprecated libc4 code w=
as
    accidentally kept in `implicit_soname`, instead of the libc6 code.

    This causes additional symlinks to be created by `ldconfig` for librari=
es
    without a soname, e.g. a library `libsomething.123.456.789` without a
soname
    will create a `libsomething.123` -> `libsomething.123.456.789` symlink.

    As the libc6 version of the `implicit_soname` code is a trivial `xstrdu=
p`,
    just inline it and remove `implicit_soname` altogether.

    Some further simplification looks possible (e.g. the call to `create_li=
nks`
    looks like a no-op if `soname =3D=3D NULL`, other than the verbose prin=
tfs),
but
    logic is kept as-is for now.

    Fixes: BZ #30125
    Fixes: 8ee878592c4a ("Assume only FLAG_ELF_LIBC6 suport")
