trimming: Remove init.c from test (#58197)

This accidentally diverged when #58141 was merged without adjusting the
test to match (these tests shouldn't be re-implementing the `juliac`
link step anyway, but they currently do)

Unfortunately, this hid a bug where `jl_pathname_for_handle` does not
understand the main executable.
