do not unlink ior-rnd file if the phase was not run

[mchaarawi]

we can probably just add a check here:

diff --git a/src/phase_ior_rnd_write.c b/src/phase_ior_rnd_write.c
index 0ca1e63..5772a60 100644
--- a/src/phase_ior_rnd_write.c
+++ b/src/phase_ior_rnd_write.c
@@ -30,7 +30,8 @@ static void cleanup(void){
     unlink(filename);
   }
   if(opt.rank == 0){
-    u_purge_file("ior-rnd/file");
+    if (opt.mode != IO500_MODE_STANDARD)
+      u_purge_file("ior-rnd/file");
     u_purge_datadir("ior-rnd");
   }
 }

The PR in #31 should fix this issue.

I actually tried that, but that doesn't work because we still create the ior-rnd dir, but we don't delete it since we don't cleanup. And then when we try to rm the datadir that fails because that is not empty.

Modified the PR to also run creation (and validate) only if needed.
