Historical pytensor versions that ship the numba disk-cache infrastructure but predate pymc-devs/pytensor#1992 crash on LLVM symbol-mangling collisions when asv's two-phase Build->Eval benchmark hits the numba cache across process boundaries. Patch the installed pytensor in place from the provisioner so the timeline keeps building cleanly on those commits without disabling the numba cache (which would change what we're measuring).

Cherry picked from #1988
Issue comes from LLVM symbol mangling of caches created across os.fork processes. LLM "thought" dump in numba/numba#10486
Functions with the same name + input signature would get messed up. PyTensor knows these are different (they have a different cache key). To avoid this we put the signature in the name of the wrapper cached function as well.
