LOG: [LLDB] Fix ASAN tests on newer versions of macOS (#165883)

macOS forbids injecting the ASAN runtime into system processes when SIP
is enabled. That includes the just-built libLTO that the just-built
clang injects into the system linker. Since we don't test the compiler
here, just use the system (non-asanified) LTO library to make ASAN tests
work for most users, including the bots.
