classpath: bump to version 0.99

classpath: bump to version 0.99

Drop both patches since they are included upstream.
We don't need to autoreconf now.

Note: classpath 0.99 has a bug in it's autoconf scripts, such that
configure always fails when specifying --disable-tools[1].
We enable these for now.

Also explicitly disable GJDoc generation, as this defaults to on now.
--disable-plugin is not needed any more, since this is now the default.
