Use __ehdr_start rather than _begin in _dl_start_final
__ehdr_start is already used in rltld.c:dl_main, and can serve the same purpose as _begin. Besides tidying the code, using linker defined section relative symbols rather than "-defsym _begin=0" better reflects the intent of _dl_start_final use of _begin, which is to refer to the load address of ld.so rather than absolute address zero.
