[OE-core] [PATCH V2] oe-setup-builddir: remove unreachable code, update comments

[Darren Hart]

From: Darren Hart <dvhart at linux.intel.com>

The script forces TEMPLATECONF to be non-empty with:

    TEMPLATECONF=${TEMPLATECONF:-meta/conf}

This ensures that OELOCALCONF and OELAYERSCONF will be non-empty as well. Remove
all the empty checks for these variables.

While this patch doesn't change behavior, all this code was unreachable, it does
bring up a point of intent. It appears as though OE*CONF was intended to be
configurable by the user via the environment, the code only allows for the user
to set TEMPLATECONF. This means that in order to use something other than the
sample default configs, the user must specify both a local.conf.sample and a
bblayers.conf.sample in their TEMPLATECONF directory.

Update the comments to correctly identify the required files as local.conf.sample
and bblayers.conf.sample.
