test(patcher): gate x64-only property_device alternate-form tests off x86

The two alternate-form-via-Jcc-target tests feed x64 synthetic machine code and
the analyzer decodes with the host arch_bits(), so they fail under
target_arch=x86 (i686 CI test job). Gate them with cfg(not(target_arch = "x86")).
Test-only change; shipped binaries are unchanged (v0.3.0 release artifacts stand).
