build.zig: teach `--compress-debug-sections`
Now that #11863 is landed, let's expose it to the zig programs that
build stuff via `build.zig`. "Benchmarks" with [turbonss](https://git.sr.ht/~motiejus/turbonss):
Built with:
$ zig build -Dtarget=x86_64-linux-gnu.2.19 -Dcpu=x86_64_v3 -Drelease-small=true
