Log Message:
The thttpd tarball has changed (the e-mail address of the author was
changed all through it).  While there, make the package correctly fetch the
NetBSD logo.

Bump PKGREVISION, and after that I'll delete the copy ftp.netbsd.org
currently has.  The tarball change doesn't happen often enough for this
package to justify the use of DIST_SUBDIR (and that avoids the hairy
problem of sharing the sitedrivenby.gif file).
