package_rpm.bbclass: NO_RECOMMENDATIONS support

Add NO_RECOMMENDATIONS support.  A way to disable all recommended
packages from being installed.  This will help shrink the size of
the resulting filesystem.

Add documentation on NO_RECOMMENDATIONS and BAD_RECOMMENDATIONS.

Note, using NO_RECOMMENDATIONS has side effects such that kernel-modules may
not have been installed.  A user will need to manually add to their image
any kernel-modules required to be on the image for functionality.
