[OE-core] [PATCH 3/4] devtool: Load plugins in a well defined order

From: Ola x Nilsson <ola.x.nilsson at axis.com>
To allow devtool plugins in one layer to shadow another in a well
defined way, first search BBPATH/lib/devtool directories and then
scripts/lib/devool and load only the first found.
The previous search and load loop would load all found plugins with the
ones found later replacing any found before.
