[PATCH v2 16/22] run-command.c: make "struct parallel_processes" const if possible

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Add a "const" to two "struct parallel_processes" parameters where
we're not modifying anything in "pp". For kill_children() we'll call
it from both the signal handler, and from run_processes_parallel()
itself. Adding a "const" there makes it clear that we don't need to
modify any state when killing our children.
