Fix a compile break in mod_mime_magic.c. In early 2.0 versions, we would

get a pipe back from create_child, and stuff that into a buff to read from
it.  This made sense in 1.3, because we got a buff back from the
create_process call.  In 2.0, we are getting a pipe, so this doesn't
make sense.  This patch just uses the pipe that is returned to us to read
the information we want.
