Clang package: bundle "ubsan_standalone*" isntead of "ubsan*" libraries.

Apparently there also is ubsan_minimal runtime which we do not use:
https://clang.llvm.org/docs/UndefinedBehaviorSanitizer.html#minimal-runtime.

It's fairy small though:

20K	libclang_rt.ubsan_minimal-i386.a
20K	libclang_rt.ubsan_minimal-i386.so
24K	libclang_rt.ubsan_minimal-x86_64.a
4.0K	libclang_rt.ubsan_minimal-x86_64.a.syms
20K	libclang_rt.ubsan_minimal-x86_64.so
