x86: fix build error and kconfig for ia32_emulation and binfmt

Fix kconfig warning and build errors on x86_64 by selecting BINFMT_ELF
when COMPAT_BINFMT_ELF is being selected.

warning: (IA32_EMULATION) selects COMPAT_BINFMT_ELF which has unmet direct dependencies (COMPAT && BINFMT_ELF)

fs/built-in.o: In function `elf_core_dump':
compat_binfmt_elf.c:(.text+0x3e093): undefined reference to `elf_core_extra_phdrs'
compat_binfmt_elf.c:(.text+0x3ebcd): undefined reference to `elf_core_extra_data_size'
compat_binfmt_elf.c:(.text+0x3eddd): undefined reference to `elf_core_write_extra_phdrs'
compat_binfmt_elf.c:(.text+0x3f004): undefined reference to `elf_core_write_extra_data'

[ hpa: This was sent to me for -next but it is a low risk build fix ]
