Akin r302691 in head, synchronize the build stripping for the disc1
image with that of the bootonly image (but similarly modulo games
and groff(1)) as the amd64 disc1 image is overflowing. This also
removes the redundant MK_LLDB.

This is a direct commit to stable/11 rather than a MFC of r302691 as
the the disc1 image stripping previously has been directly modified
in stable/11 by r303027.

Reduce the disc1.iso size from 850+M to just over 650M.

As a result of this change, the 'kernel-dbg.txz' distribution
is no longer provided on disc1.iso, and deselected by default
in bsdinstall(8). When 'kernel-dbg.txz' is selected, network
configuration happens before the installer proceeds, to fetch
the distribution from the mirrors.

This is a direct commit to stable/11, as there is intention
to solve this differently for 12.0-RELEASE.
