Use a function instead of find to delete all job's config.xml

Find recurse into all the directories under the jenkins home to
find the jobs/XXXX/config.xml files. Instead, a method recursing only
into jobs folder let us skip all other directories (builds,
configurations, etc...). This slowness was not discovered on staging
because staging has less way build that the prod instance.

Tested for speed on the jenkins master without deleting the files
(just echoing)

Tested for correctness by deploying to staging.
