Move binary check to CRLF filter itself

Checkout should not reject binary files from filters, as a filter
may actually wish to operate on binary files.  The CRLF filter should
reject binary files itself if it wishes to.  Moreover, the CRLF
filter requires this logic so that users can emulate the checkout
data in their odb -> workdir filtering.
