selftests/x86: Disable tests requiring 32-bit support on pure 64-bit systems
The ldt_gdt and ptrace_syscall selftests, even in their 64-bit variant, use hard-coded 32-bit syscall numbers and call "int $0x80". This will fail on 64-bit systems with CONFIG_IA32_EMULATION=y disabled. Therefore, do not build these tests if we cannot build 32-bit binaries (which should be a good approximation for CONFIG_IA32_EMULATION=y being enabled).
