Improved master branch build setup

Modify checkout_atlasexternals.sh to use a default clone URL
which is https+krb5. Also allow this to be changed with a
command line switch. N.B. Still requires support from the
higher level script Projects/Athena/build_externals.sh.

Change the Athena project package build list. Remove
analysis only packages that should not build here. Also filter
out many generator packages for now until these can be fixed
properly. Lack of generators disables fast simulation.
