linux-gen: x86: sysinfo: fix cpu_isa_sw.x86 in 32-bit x86

The ODP_CPU_ARCH_X86_I686 value in odp_system_info_t::cpu_isa_sw.x86
indicates the IA32 ISA, but in the implementation the value is used
only when __i686 or __i686__ is defined. In many x86_32 systems this
causes sysinfo to return ODP_CPU_ARCH_X86_UNKNOWN in cpu_isa_sw.x86,
which in turn fails API validation test.

Fix the problem by recognizing IA32 ISA from the __i386 or __i386__ macro.
