Introduce a no-perfprofd module.

This module creates a dummy binary that can be used to replace
perfprofd on some build products. Its intended (temporary) use is to
regain some space on the system partition of storage-constrained
products such as marlin-eng and sailfish-eng.

Test: lunch marlin-eng && make systemimage
