Disable unpack/build fusion

unpack/build on bytestrings seems to trigger a bug when interacting with
head/build fusion in GHC.List. The bytestring001 testcase catches it.

I'll investigate further, but best to disable this for now (its not
often used anyway).

Note that with -frules-off or ghc 6.4.2 things are fine. It seems to
have emerged with the recent rules changes.
