[compiler-rt][test] Set shared_libasan_path in test/asan/lit.cfg on Solaris

[ro]

Summary

While checking warnings from the Solaris buildbots, I noticed

llvm-lit: /opt/llvm-buildbot/home/solaris11-amd64/clang-solaris11-amd64/llvm/projects/compiler-rt/test/asan/lit.cfg:119: warning: %shared_libasan substitution not set but dynamic ASan is available.

Fixed as follows. Tested on x86_64-pc-solaris2.11. Ok for trunk?

[ro]

Sorry, wrong patch.
