tests/mknod.c: add workaround for ppc bug in travis

On ppc travis builds syscall(mknod) sometimes does not fail with EEXISTS
as expected, but returns successfully. This commit uses sprintrc for
errno printing, which handles successful return values too.

* tests/mknod.c (main): Use sprintrc for printing errno.
