    elf: Remove redundant _dl_map_segments declaration from dl-load.h
    
    The function `_dl_map_segments` is defined in `<dl-map-segments.h>`,
    which provides the canonical implementation (optionally overridden
    by sysdeps variants). All call sites include `<dl-map-segments.h>`
    directly, so declaring `_dl_map_segments` in `dl-load.h` is unnecessary.
    
    Keeping a static prototype in `dl-load.h` can trigger
    -Wunused-function errors when the header is included by translation
    units that do not include `<dl-map-segments.h>` and do not reference
    `_dl_map_segments`. Since glibc builds with `-Werror`, this results
    in build failures [1].
    
    Remove the redundant declaration from `dl-load.h` to avoid these
    spurious warnings and keep the declaration colocated with the
    definition as intended.
