chore(profiling): fix sanitizers on Linux

[sanchda]

In order for our tests to work with sanitizers,

• sanitizer lib needs to be propagated from the test fixture to the dynamic libraries (e.g., dd_wrapper) (this was broken due to underspecifying the link type)
• dynamic linker needs to be able to find the .so; the way we did it worked OK on macos, but on Linux the libs are actually in a subdir
