add easyconfig for BEDTools v2.22.0 with intel/2014b

Well, it's 1276 vs 1230, so there are slightly more `source_urls` after `sources` than the other way around :wink:

I don't really care in which order they are,  just that we try to be consistent and as the `TEMPLATE.eb` puts `sources` first, I would take that as the default.
