Update buildroot

Update buildroot (branch cesnet/2023-06-12). This also contains a patch
to fix libcurl build[1] which I had on my local dev machine.

New buildroot also builds systemd 252.4 so necessary patch update added.

Also added perl-English package to our CI machines to silence the
following build error:

  2023-06-12 12:42:55.964693 | w | Your Perl installation is not complete enough; at least the following
  2023-06-12 12:42:55.964825 | w | modules are missing:
  2023-06-12 12:42:55.964844 | w |
  2023-06-12 12:42:55.964856 | w | 	 English
  2023-06-12 12:42:55.964866 | w |

Systemd 252 added naming scheme for net links with devicetree
aliases[2]. This renames our eth{0,1} to end{1,2} which is undesirable
because the boxes physical ports are labelled eth{0,1,2}. Oh and I forgot:
The network does not start after the boot because we expect the names
to be eth{0,1}. So let's make sure our names stay eth{0,1,2}.
