sim: cris: fix C tests with newer toolchains

Make sure we include unistd.h for getpid prototypes to fix build
warnings/errors with newer compilers & C libraries.

Doing that for close in openpf highlights these were using the
wrong function -- need to use fclose on FILE*, not close.

These tests pass again with a cris-elf toolchain.
