Adding a const to a static char array

When a different static char broke the build (for unrelated
reasons), I looked through the tree for other static chars without
const. This was the only other one outside third_party and tests.

It's possible the generated machine code is the same, or it might
become better this way. Depends on the compiler/linker/OS.
