autobuild: extend autobuild with samba-fuzz job to build the fuzzers in AFL mode using oss-fuzz scripts
This helps ensure the build_samba.sh file keeps working and the fuzzers build
(because they are excluded from the main build).
This is not in the default autobuild because it uses too much
space on sn-devel (4GB).
