Don't export UBSan minimal runtime symbols.

When linking in the UBSan minimal runtime, don't export the symbols.
This was resulting in an edge case where symbols were sometimes
undefined at runtime on address sanitized builds if static library
dependencies were integer overflow sanitized.

Bug: 78766744
Test: readelf on libraries show either inclusion of the shared library
or no undefined symbols related to the minimal runtime.
