[lldb][test] Skip libsanitizers tests for now (llvm#130305)

These are macOS tests only and are currently failing on the x86_64 CI
and on arm64 on recent versions of macOS/Xcode.

The tests are failing because we're stopping in:
```
Process 17458 stopped
* thread #1: tid = 0xbda69a, 0x00000002735bd000
  libsystem_malloc.dylib`purgeable_print_self.cold.1, stop reason = EXC_BREAKPOINT (code=1, subcode=0x2735bd000)
```
instead of the libsanitizers library. This seems to be related to
`-fsanitize-trivial-abi` support

Skip these for now until we figure out the root cause.

(cherry picked from commit 6cc8b0b)
