pkg/ifuzz/iset: rename ifuzzimpl to iset

ifuzzimpl is too lenghty and too clumsy on my taste
(nm/vmimpl worked better b/c it's shorter and used less).
I've tried to come up with something shorter and nicer.
We could use "insn" as a common name for "instruction" in ifuzz,
but it's a commonly used name already so would cause lots of conflicts.
"iset" is somewhat descriptive, short and nice.
