ver_linux: proc/modules, limit text processing to 'sed'
This patch is more of a personal preference, rather than a fix for a problem.
The current implementation used a combination of both 'cat' and 'sed'
to generate an unsorted list of kernel modules separated by while space.
The proposed implementation uses 'sort' and 'sed' to generate a sort
list of kernel modules separated by while space.
Tested on:
Gentoo Linux
Debian 6.0.10
Oracle Linux Server release 7.1
Arch Linux
openSuSE 13.2
