While cleaning up old libc version support, the deprecated libc4 code was accidentally kept in `implicit_soname`, instead of the libc6 code. This causes additional symlinks to be created by `ldconfig` for libraries 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 `xstrdup`, just inline it and remove `implicit_soname` altogether. Some further simplification looks possible (e.g. the call to `create_links` looks like a no-op if `soname == NULL`, other than the verbose printfs), but logic is kept as-is for now.
