Subject: meta-agl-lxc: Update host kernel configuration

Add a generic kernel bbappend and associated conditional include
file that uses the new AGL_KCONFIG_FRAGMENTS to disable all other
AGL provided kernel configuration, replacing it with a local fragment
to enable minimal required features for LXC support.  The previous
linux-renesas bbappend to leverage the meta-virtualization provided
kernel configuration has been removed, and the agl-lxc template has
been updated to drop the "virtualization" distro feature (thus
disabling all meta-virtualization additions).

Bug-AGL: SPEC-3983
