linux-wrs: allow optional features via KERNEL_FEATURES variable

Fixes [BUGID #199]

Reinstate the ability to specify optional/additional kernel features
when updating the tree.

This is done via the variable KERNEL_FEATURES which specifies
a list of features to be appended to the current branch and
config. These features are part of the wrs_meta branch in the
kernel repository and hence are self contained within the
kernel tree waiting to be activated. This saves multiple
branches simply to allow a machine to have many profiles.

The kernel patching/configuration phases will locate these
features and add them to the meta_series, which in turn
modifies the tree.
