tools/gn: include exec_process.h in the source file.
exec_process.cc is the source file implementation of exec_process.h,
but somehow we forgot to include its corresponding header file. This
patch fixes that.
It also add it to the unittest file where it was also missing.
build_config.h was also included for the usage of OS_XXX macros.
