 Fix #8754 in a round-about way.

 For some reason on OS X, it seems like -Bsymbolic (which we use for
 hooks into the RTS) isn't working, which results in #8754, where stats
 don't work because defaultHooks doesn't initialize the stats flag. This
 seems to work on Linux static/dynamically, but only on OS X statically.

 After talking with Simon, really, the entire hooks thing is a bit
 fragile. For now, we just work around it (since GHCi is dynamically
 linked) by calling into the defaultHooks ourselves when GHC starts.
