[Bug 1736421] [NEW] Linux boot parameters are not taken to busybox environment

[Stefan]

Public bug reported:

With busybox 1.27.2 (18.04 installer system), my kernel command line
parameters that contain "/" or "-" are stripped and not in environment,
anymore (e.g. keyboard-configuration/modelcode=SKIP). Furthermore, the
parameters are not pushed into debconf database by script env2debconf
(where I would need them).

I found this already fixed in busybox, here is the commit:
https://git.busybox.net/busybox/commit/shell/ash.c?id=9c143ce52da11ec3d21a3491c3749841d3dc10f0

Here is the issue:
https://bugs.busybox.net/show_bug.cgi?id=10231

I tested this by patching ash.c (patch is attached), building it and
integrated into initrd.gz - works, parameters are in environment, again.

It would be fine if this patch could get into busybox package for 18.04.
