[PATCH] cr_test: include unistd.h for syscall numbers

[PATCH] cr_test: include unistd.h for syscall numbers

[Nathan Lynch]

Instead of duplicating the checkpoint/restart/clone_with_pids system
call numbers for powerpc in cr.h, just #include asm/unistd.h and
remove the #error; the build will fail intelligibly if those constants
are undefined.

(also add guards to prevent multiple inclusion)
