smb.conf.5: sort parameters alphabetically

smb.conf.5: sort parameters alphabetically

Content of each separate parameter description file is added
into a parameters.all.xml file before compiling smb.conf.5.

The issue is that POSIX file systems generally don't give any
promises over how glob-produced files are sorted. Thus, we need to sort
them in a predictable way.

This patch adds sorting based on a file name as a string. Since all
parameter files named after the parameter itself (plus .xml), we can
use file name sorting.
