[oe] [PATCH] jakarta-libs: fix SRC_URIs for avalon-framework, logkit

[Jesse Gilles]

Please apply to 2011.03-maintenance.  Without this patch, building
openjdk from scratch (no sources dir) fails because the
avalon-framework-api tarball can't be downloaded.  Apache.org put up a
placeholder page for http://www.apache.org/dist/excalibur/ that ends up
getting downloaded instead of the tarball.

Thanks,
Jesse
