Add dup_body_fh to return a dup'd body FH

Browse Source 
It wasn't suitable to dup the body FH returned by plain old
body_fh(), so here's a separate function to return that.

=head2 dup_body_fh( )
Returns a dup()'d file handle to the temporary file of the email. This can be
useful if an external module may call close() on the filehandle that is passed
to it. This should only be used for reads, as writing to a dup'd filehandle
may have unintended consequences.
