[lld][cmake] Fix BUILD_SHARED_LIBS installation

Summary: This fixes a regression caused by D28397, which switched lld from using add_llvm_library to llvm_add_library. The latter does not automatically set up install rules for libraries, as it's expected the project will set them up manually based on its own needs. This adds the install rules to add_lld_library for lld. They were inspired by the similar add_clang_library macro in clang.
