    x86/EFI: don't have an overly large image size
    
    While without debug info the difference is benign (so far), since we pad
    the image to 16Mb anyway, forcing the .reloc section to a 2Mb boundary
    causes subsequent .debug_* sections to go farther beyond 16Mb than
    needed. There's no reason to advance . for establishing __2M_rwdata_end,
    as all data past _end is of no interest at runtime anymore anyway.
