Subject: [PATCH 1/1] Generate lxc-restore-net properly

It's a script that should be run through the configure
mechanism the same as the others.  We simply rename it
to have a .in extension and add it to configure.ac .

Also, by generating the script from a .in file, it gets
placed into the build directory.  This plays nice with
build systems that keep the src separate from the build
directory.  Without this change, the install step won't
find the lxc-restore-net script as it still just resides
in the src directory and not in the build directory.

Upstream-Status: Not applicable.  This script has already
been rearchitected out of existence by
cba98d127bf490b018a016b792ae05fd2d29c5ee:
"c/r: use criu option instead of lxc-restore-net

As of criu 1.5, the --veth-pair argument supports an additional parameter that
is the bridge name to attach to. This enables us to get rid of the goofy
action-script hack that passed bridge names as environment variables.

This patch is on top of the systemd/lxcfs mount rework patch, as we probably
want to wait to use 1.5 options until it has been out for a while and is in
distros.
