[NFCI][bolt][test] Enable AT&T syntax generally (#172355)

Browse Source 
Having it in the X86 subdirectory only affects tests in that directory.
That's however not sufficient as for example runtime/X86/pie-exceptions-split.test is affected but
isn't located in the X86 directory.
This essentially fixes the fix for the original commit by guarding it properly for when the X86
target has been built and the flag is recognized.
