OCPBUGS-83863: Strip debug symbols from Go binaries

[sdodson]

Summary

• Add -s -w to ldflags in .promu.yml to strip DWARF debug info and symbol tables

Impact

The prometheus-node-exporter image (323 MB) contains one unstripped Go binary:

• node_exporter (23.2 MB)

Stripping typically reduces Go binary size by 20-30%, reducing container image pull time during node scale-up.

Test plan

• Verify image builds successfully
• Verify binary is stripped
• Verify node_exporter functions correctly
