[PATCH] tests/tcg/aarch64: Fix test-mte.py

[Richard Henderson]

Python 3.12 warns:

  TEST    gdbstub MTE support on aarch64
/home/rth/qemu/src/tests/tcg/aarch64/gdbstub/test-mte.py:21: SyntaxWarning: 
invalid escape sequence '\('
  PATTERN_0 = "Memory tags for address 0x[0-9a-f]+ match \(0x[0-9a-f]+\)."

Double up the \ to pass one through to the pattern.
