Use `Base.fixup_stdlib_path` in paths printed in e.g. `ascend`

Right now, links to stdlibs are those of the build machine:

Choose possible caller of MethodInstance for Pkg.Types.Compat(::Pkg.Versions.VersionSpec, ::Any) or proceed to typed code:

There is a Base.fixup_stdlib_path function that fixes this:

julia> Base.fixup_stdlib_path("/Users/administrator/.julia/scratchspaces/a66863c6-20e8-4ff4-8a62-49f30b1f605e/agent-cache/default-macmini-aarch64-1.0/build/default-macmini-aarch64-1-0/julialang/julia-master/usr/share/julia/stdlib/v1.10/Pkg/src/project.jl")

I've got a local fix for this in Cthulhu, I'll run it for a little while to make sure it's working.

Fixed (long ago) in JuliaDebug/Cthulhu.jl#579
