    x86: Fix DT_JMPREL/DT_PLTRELSZ when relocs share a section

    If a linker script does not place the PLT relocations and "normal"
    relocations in separate ELF sections, `ld` will currently output incorrect
    values for DT_JMPREL and DT_PLTRELSZ - they cover the entire ELF section,
    rather than just the PLT relocations

    Don't ignore the extent of the BFD section - use the size of the srelplt
    BFD section and its offset from the output_secttion
