[PATCH] ci: container: build openssl against musl

[Thomas Bonnefille <thomas.bonnefille@bootlin.com>]

Since 3c739b95ee ("sandbox: enable keytoc in hosttools_defconfig") the
hosttools_defconfig also builds keytoc a tool required to inject
cryptographic keys in a device tree.
This software needs openssl to be compiled. However, as barebox-ci is
using Debian as the base of its container, the openssl package given by
apt is compiled with the glibc.

In order to compile keytoc with musl, build a version of openssl against
musl in the barebox-ci container.

Hello, I added the support to build openssl against Musl, this fixes the
commit 3c739b9 in CI.
Another patch has been sent previously to fix this issue
(https://lore.kernel.org/barebox/20260805142055.3844660-1-a.fatoum@pengutronix.de/)

I didn't find it in the 'next' branch of the Github repository
(git.pengutronix.de seems down on my side) and I assumed it wasn't
applied so I didn't include a revert commit for it.
