Inherit TCC in debuginfo tests on macOS

macOS has a system for propagating folder permissions, which LLDB disables when spawning processes, which in turn causes debuginfo tests to spam the user with repeated pop-ups asking for permissions. See the code comment for details, as well as the following video for an example of how this looks in practice:

I stumbled upon the incantation to fix this (`settings set target.inherit-tcc true`) while investigating slowdowns when spawning newly created binaries due to XprotectService, see [this Zulip thread](https://rust-lang.zulipchat.com/#narrow/channel/246057-t-cargo/topic/build.20scripts.20slow.20on.20macOS.3F).

This would allow me to no longer have a `build.build-dir = "/Users/madsmtm/rust-build"` workaround in my `bootstrap.toml`.
