Reapply "[compiler-rt][HWAsan] Remove CHECK lines from test" (#167038)

This reverts commit cc8478b.

This was exposing existing failures due to the removal of the || clause
in the run lines due to address space conflicts. Move the fixed base
lower than the libraries will ever end up being to resolve the issue.
