While here, don't install the whole jsdk20 environment, as this is an older
version, and is generally useful only in order to get the jsdk20 jar file
for building jserv. This means we no longer install the bin/servletrunner
test harness, and we no longer install the jsdk source.
Users interested in these would be better off looking at the current jsdk
(pkgsrc/www/jakarta-tomcat), or jsdk2.1, which does not currently have
a package, but is at least rather less obsolete...
jserv will be adapted to use the new paths for this in a separate commit,
in a few minutes.
