d/p/0004: Add a patch to make systemd security features working in unprivileged containers in nesting apparmor profile. This can cause security risks in privileged containers, so it's only in nesting profile.

Upstream release 5.0.1

This is already handled by the upstream build system.

Closes: #1004978

The code that actually uses bridge-utils (brctl) has been ported over to
use `ip` from iproute2 some time ago.

Closes: #1004733

This is to host the shared components needed by both bin:lxc and a potential future bin:lxd

Closes: #1002564

Remove bridge-utils from lxc's dependencies and prioritize nftables over iptables as a firewalling dependency

Closes: #908050

Update to upstream version '4.0.11'
with Debian dir 5356cc2ff48b283f860d8b8e1db996094ab48dba

Replace deprecated 'which' with 'command -v'

See merge request !13

This fixed the following warning:
"/usr/bin/which: this version of `which' is deprecated; use `command -v'
in scripts instead."

Closes: #1003591
