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 *Debug, uncompressed* 174K turbonss-analyze 161K turbonss-getent 1.2M turbonss-unix2db 448K libnss_turbo.so.2.0.0 *Debug, compressed* 78K turbonss-analyze 86K turbonss-getent 572K turbonss-unix2db 190K libnss_turbo.so.2.0.0 *Stripped, for completeness* 17K turbonss-analyze 20K turbonss-getent 197K turbonss-unix2db 26K libnss_turbo.so.2.0.0
