patch: httpd(8) use LOG_FTP for transfers, like $DEITY intended

[zeurkous]

#?patch
#
# This patch corrects the logging of transfers, of OpenBSD's httpd(8),
# to xferlog, where it belongs.
#
# A simple patch to a waaay overcomplicated bit of software (with insane
# defaults to boot; security anyone?).
