sort?

Oh, right. This is the order they're displayed in the waterfall, but I realize
now that only matters for the spec listing below, so I've sorted this now.

[kjellander_chromium, 2015/10/15 12:08:40]

From reading the code it looks like the behavior is different when
'slavebuilddir' is missing and when it exists but has a value of None. Because
of that I didn't want to risk changing behavior, which led to this solution.

Previously all builders had it set, but I know from previous experience that if
it's not set, the builder will get a slave build dir named similarly to the
builder name, which is fine with ours, since there aren't that many different
builders sharing the same machines.

+      builder_dict['slavebuilddir'] = spec['slavebuilddir']
+
+    c['builders'].append(builder_dict)
