[PATCH 1/2] test: include headers for used funcs

[Mike Frysinger]

These funcs use things like wait/write/read/strcmp but sometimes don't
include the right header for them.

* Makefile: Add -Wall to CFLAGS.
* clone.c: Include unistd.h.
* fork.c: Include sys/wait.h.
* sig.c: Include unistd.h.
* sigkill_rain.c: Include sys/wait.h.
* vfork.c: Include sys/wait.h.
* wait_must_be_interruptible.c: Include string.h
