fix swallowing internal errors in precompilepkgs

[IanButterworth]

Testing:

• with a package error

(SimpleLooper) pkg> precompile
Precompiling all packages...
  ✗ SimpleLooper
  0 dependencies successfully precompiled in 2 seconds

ERROR: The following 1 direct dependency failed to precompile:

SimpleLooper 

Failed to precompile SimpleLooper [ff33fe5b-d8e3-4cbd-8bd9-3d2408ff8cab] to "/Users/ian/.julia/compiled/v1.12/SimpleLooper/jl_PQArnH".
ERROR: LoadError: 
Stacktrace:
  [1] error()
    @ Base ./error.jl:53

• with interrupt

  1 dependency had output during precompilation:

• an internal error simulated in the same scope that [1.10] precompile silently dies due to SystemError when opening .ji files Pkg.jl#3984 was failing to throw from

FWIW, it might be a good idea to prune all of the:

┌ SimpleLooper
│  [57879] signal 2: Interrupt: 2
│  in expression starting at /Users/ian/Documents/GitHub/SimpleLooper.jl/src/SimpleLooper.jl:2
└  

while we're at it - they are a lot of noise

[IanButterworth]

Definitely. I haven't come up with a good (non brittle) design for that given there might be output before the interrupt.
