    aarch64 (arm64) isn't a supported architecture for exp-sgcheck.
    
    exp-sgcheck/pc_main.c contains:
    
       #if defined(VGA_arm) || defined(VGA_arm64)
          VG_(printf)("SGCheck doesn't work on ARM yet, sorry.\n");
          VG_(exit)(1);
       #endif
    
    But exp-sgcheck/tests/is_arch_supported checked against uname -m
    which returns aarch64 (not arm64). Fix the test check so the
    exp-sgcheck tests are skipped instead of producing failures.
