cmake: accept versioned libatomic.so.1 in find_library
    
    openSUSE's `libatomic1` package ships only `libatomic.so.1` —
    there's no separate -devel package, and therefore no unversioned
    `libatomic.so` symlink, so the previous `find_library(NAMES atomic)`
    failed even though the library was installed.
    
    Accept `libatomic.so.1` as a fallback name. The canonical
    unversioned name is kept first so distros that do ship the symlink
    (Debian / Fedora / Arch) still resolve to it. Also tag the STATUS
    line with the resolved path so the chosen variant is visible in the
    configure summary.
