Change back to linux_blink_oilpan_rel in MB config.

After we changed most of the oilpan bots to be named
"non-oilpan", we started getting an error because the
experimental linux_blink_oilpan_rel bot on
tryserver.chromium.linux did not get renamed on the
waterfall but did get renamed in mb_config.pyl .

Changing the bot name on the waterfall is somewhat annoying,
so for the moment we'll change the entry in MB instead.
