Commit b4fc5a180c (package/busybox: support spaces in module aliases in
mdev) changed the mdev coldplugging to handle sysfs path elements and
modalias values containing spaces. This unfortunately doesn't work as was
recently reported:
http://lists.busybox.net/pipermail/buildroot/2018-May/220903.html
The problem is that sort -z also expects the fields of the input files to be
zero terminated, which is not the case for modalias sysfs entries.
So drop the -z option to sort. Spaces in modalias entries could be handled
with the xargs -d '\n' option, but that is unfortunately not supported by
the busybox applet. Instead, use tr to convert newlines to zeros so we can
use xargs -0.
