[PATCH master 2/2] defaultenv: devboot: use rsinit.bind_modules to bind mount modules

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

From: Ahmad Fatoum <a.fatoum@barebox.org>

The rsinit-modules snippet and the devboot documentation pass
rsinit.bind=/lib/modules on the kernel command line, but rsinit only
knows the rsinit.bind_modules flag and silently ignores unknown
options. The modules CPIO is thus unpacked into the initramfs, but
never bind mounted over the root file system's /lib/modules.

Switch both over to rsinit.bind_modules.

Fixes: 1003a9d70373 ("defaultenv: base: add new devboot script")
Fixes: fc586dda711c ("defaultenv: add optional devboot snippets under /env/devboot/")
