Skip TestVariableAnnotationsDisassembler.py on non-x86 architectures

The test TestVariableAnnotationsDisassembler.py relies on an .s input file generated for x86_64 with assembly directives that are not portable (e.g., DWARF sections and comments using #).
This causes build failures on non-x86 targets such as AArch64.

This change skips the test unless the architecture is x86_64, ensuring it only runs where the assembly input is valid.
