Cure Bitbake warnings

These trivial updates are intended to cure the
following Bitbake warnings:

WARNING: Layer tiogapass-layer should set
LAYERSERIES_COMPAT_tiogapass-layer in its
 conf/layer.conf file to list the core layer names
  it is compatible with.

WARNING: No bb files matched
BBFILE_PATTERN_tiogapass-layer ''

Compatibility was previously not specified. Also,
the BBFILE_PATTERN did not point to the layer
directory.

A warning will still be generated regarding no BB
files at the Facebook layer because there aren't
any present at this time. However, this patch
makes it look in the correct place when there are
BB files present.
