Build: Always use local tmp dir on macOS.

[Gacko]

What this PR does / why we need it:

mktemp -d evaluates to something like /var/folders/bn/r2_ys7nn0rg25npypt36m8rw0000gn/T/tmp.FYBRndtt3l on macOS. In a restricted environment where you allow directories to be used as bind volumes selectively, you cannot easily configure this path in Docker Desktop and therefore would need to share the whole /var/folders directory, which is not justified for this use-case.

I therefore changed the if to always create a tmp in the current directory (mostly the project's root directory) on macOS.
