Add 'disksup_posix_only' parameter to disksup
On embedded (Linux) systems the "df" program is very often provided by the Busybox (or Toolbox) project. This version does not provide the "-l" option (for displaying only local filesystems) used in disksup.erl. To make disksup work on these embedded platforms, this patch adds a new application parameter 'disksup_posix_only', to make diskup use only options defined in the POSIX standard: http://pubs.opengroup.org/onlinepubs/9699919799/utilities/df.html
