[ASan][test] XFAIL stack overflow tests on Linux/sparc64

[rorth]

When enabling ASan SPARC testing as per PR #107405, 3 stack overflow tests FAIL on Linux/sparc64:

  AddressSanitizer-sparc-linux :: TestCases/Linux/stack-overflow-recovery-mode.cpp
  AddressSanitizer-sparc-linux :: TestCases/Linux/stack-overflow-sigbus.cpp
  AddressSanitizer-sparc-linux :: TestCases/Posix/stack-overflow.cpp
  AddressSanitizer-sparc-linux-dynamic :: TestCases/Linux/stack-overflow-recovery-mode.cpp
  AddressSanitizer-sparc-linux-dynamic :: TestCases/Linux/stack-overflow-sigbus.cpp
  AddressSanitizer-sparc-linux-dynamic :: TestCases/Posix/stack-overflow.cpp

However, as detailed in Issue #109771, even a Linux equivalent of the Solaris/sparcv9 fix (PR #109101) doesn't improve the situation.

Therefore this patch XFAILs the tests until the root cause can be figured out.

Tested on sparc64-unknown-linux-gnu, sparcv9-sun-solaris2.11, and x86_64-pc-linux-gnu.
