documentation: remove all references to Hob

Hob and the packageinfo class have now been removed from the
code base. This patch removes all references to:

* Hob
* meta-hob
* packageinfo and
* BBLAYERS_NON_REMOVABLE

from the documentation.

So long, Hob, and thanks for all the fish.

             Be careful when deleting files in this directory.
             You can safely delete old images from this directory (e.g.
-            <filename>core-image-*</filename>, <filename>hob-image-*</filename>,
-            etc.).
+            <filename>core-image-*</filename>).
             However, the kernel (<filename>*zImage*</filename>, <filename>*uImage*</filename>, etc.),
             bootloader and other supplementary files might be deployed here prior to building an
             image.
