[ASan][test] XFAIL stack overflow tests on Linux/sparc64 (#109773)

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 `XFAIL`s 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`.
