  test: Fix race condition in headers-*.sh
  
  When running tests in parallel (e.g. using `make -j4 check`), the header
  tests currently fail due to headers-overlay.sh and headers-system.sh
  both generating headers-gen.c simultaneously, resulting in garbled
  output. Fix this by using separate C files for the tests.
