kernel.bbclass: Allow modules*.tar.gz generation to be inhibited

The modules.tar.gz archive is sometimes of no value and it can take
a noticeable time to build if many modules were enabled in the kernel
configuration.  The extraneous file also contributes to deploy/ clutter
and is a waste of disk space.

Allow it to be suppressed by setting MODULE_TARBALL_DEPLOY="0".
