fix(build): remove explicit -lasan/-lubsan from ASAN linker args

When clang++ is the compiler, -fsanitize=address links
libclang_rt.asan-x86_64.so while the explicit -lasan links GCC's
libasan.so.X from the gcc fallback path. Both end up in the binary's
NEEDED entries, causing "incompatible ASan runtimes" at startup.

-fsanitize=address/-fsanitize=undefined handle runtime linking
correctly for both GCC and clang without the explicit flags.
