devtool: finish: fix "layer not in bblayers.conf" warning when path specified
devtool finish will check if the destination layer is part of
bblayers.conf so that we avoid the user getting confused about the
recipe vanishing from their configuration if it isn't. devtool finish
also accepts a path underneath a layer so that you have a bit
more control over where it ends up. However if you used a path
underneath a layer then it wasn't converting this to the base of the
layer before checking it against BBLAYERS, thus the warning was being
shown erroneously in that case.
