feat(install): add SIGPIPE handling for Unix pipeline compatibility

[mattsu2020]

Restore SIGPIPE signal to default disposition on Unix systems if not explicitly ignored by parent, ensuring proper pipeline behavior and GNU install compatibility. The Rust runtime ignores SIGPIPE by default, but this change respects the parent's signal settings for better script integration.

Do you want to do this for each utility? I thought it's going to be needed in all utilities and would go to a central place?

Required for most utilities
Tee, yes, and watch require a different approach

In theory we could add it to the bin macro but I do not know for sure if there are any utilities that should not have this behavior? Are either of you two aware of any non-standard niche pipe signal behavior in any of the utilities?

I was checking yes and I don't see how it has a unique implementation that's different than the other utilities
