Don't construct Module() during precompilation

[serenity4]

A new error appeared for nightly, likely due to JuliaLang/julia#57425:

Failed to precompile Infiltrator [5903a43b-9cc3-4c30-8d17-598619ec4e9b] to "/home/serenity4/julia/wip8/.julia/compiled/v1.13/Infiltrator/jl_KfVJ1M".
ERROR: LoadError: Creating a new global in closed module `anonymous` (`anonymous`) breaks incremental compilation because the side effects will not be permanent.
Stacktrace:
  [1] Module
    @ ./boot.jl:574 [inlined]
  [2] Module()
    @ Core ./boot.jl:574
  [3] top-level scope
    @ ~/julia/wip8/.julia/packages/Infiltrator/cxm1l/src/Infiltrator.jl:223

The created Module() was anyway discarded with clear_store!(store) during __init__(), so this change should be safe.

[KristofferC]

Anyone package that loads this package will still hit this due to the clear_store! in __init__.

[serenity4]

Would you have an error log to share? This PR fixed an issue during precompilation, not during __init__. For the latter I wasn't aware there was another issue.

[KristofferC]

Other packages that load this will run this package __init__ where it errors. https://s3.amazonaws.com/julialang-reports/nanosoldier/pkgeval/by_hash/83dcbd4_vs_8561cc3/SnapshotTests.primary.log

[serenity4]

I see, will make a PR

[KristofferC]

Imo JuliaLang/julia#57635 should be fixed

[serenity4]

That'd be nice, as I expect many other packages to rely on this.

In the meantime, here is #136 which I'd be happy to revert at some point in the future if the situation is resolved.
