iozone: 3.506 -> 3.507

[brookst]

iozone was failing to build on my NixOS 25.05.20250307.36fd87b (Warbler) system.
Hopefully it's ok to combine a bugfix and version bump but I can separate if necessary.

The issue was that libbif.c was building without HAVE_ANSIC_C defined and was therefore not compliant C.
The error thrown was libbif.c:205:1: error: return type defaults to 'int'.
This seems to have been allowed somehow on older systems (NixOS 24.11.715344.48913d8f9127 (Vicuna) compiles successfully).
The reason for the missing flag is that the makefile doesn't explicitly define rules for all of the object files. They do get built in a rule but with enableParallelBuilding = true, make uses implicit built-in rules for the c files. I've disabled parallel building so that the implicit rules are never evaluated since the object files already exist before they are attempted. I've left a quick explanation in a comment for anyone wanting to re-enable this in future.

The new version fixes a typo with HAVE_ANSIC_C but that doesn't meaningfully change compilation. Two new options are added to the fileop utility:

     -n        Fill files with non-compressible data.
     -L        Leave files behind.
