ghc-bin.cabal.in: add a 'threaded' flag for hadrian
Summary:
hadrian will explicitly enable this flag, but more importantly needs it
as otherwise we just never end up passing -threaded to GHC when building
a new GHC binary. We could quite likely unconditionally pass -threaded,
as the corresponding logic for GhcThreaded in mk/config.mk.in seems to
always lead to it being set to True, but we instead leave a way out for
anyone in need of a GHC linked against a non-threaded runtime system in
the future.
Test Plan: T8242 (with a GHC built by hadrian)
