Fix broken foreach loop

This wasn't initializing the STATS.MODULE_TYPE.* variables, leading to
106kB of stack usage in ckati for sdk_x86_64-eng. With this fixed, the
next highest stack usage is 35kB.

Bug: 36182021
Test: Run $(flavor) over all the variables
Test: Check stack usage with custom ckati patches
Test: build-sdk_x86_64.ninja is identical before/after this change
