backends: Use elf_getshdrstrndx to find .odp section in ppc64_init
The .odp section is found by name. But ppc64_init used the e_shstrndx Ehdr field for that. This is wrong if the file contains more than SHN_LORESERVE sections. Use elf_getshdrstrndx instead to find the shstrtab section. Signed-off-by: Mark Wielaard <mark@klomp.org>
