Fix recent breakage on the HEAD.  This was caused by the fix to
Lex.lhs to treat primitive strings as "narrow" FastStrings in all
cases, rather than Unicode ("wide") FastStrings if the string
contained a '\0'.  The problem is that narrow FastStrings aren't set
up to handle strings containing '\0'.  They used to be, but it got
broken somewhere along the line.

This commit:

 - remove the '\0' test from unpackCStringBA (it takes a length
   argument anyway), and rename it to unpackNBytesBA.  This fixes
   the bug.

 - remove the '\0' terminator from all strings generated by the
   functions in PrimPacked.  The terminators aren't required,
   as far as I can tell.  This should have a tiny but positive
   effect on compile times.
