check_disk: option to ignore reserved space
This commit add a runtime option to ignore the root-reserved space
when calculating perfdata.
Before / after:
./check_disk -w 2% -c 1% /home
./check_disk -w 2% -c 1% -f /home
DISK CRITICAL - free space: /home 272 MB (1% inode=83%);| /home=17551MB;18401;18589;0;18777
DISK CRITICAL - free space: /home 272 MB (1% inode=83%);| /home=17551MB;17466;17644;0;17823
Well, it doesn't really give me more space :) but the perfdata are a
little bit more coherent.
Note that there are still a rounding issue on the percent calculation
(cf calculate_percent() comments, taken from coreutils 'df' command).
272/17823 -> 1.526%
Since the warning/critical/min/max data are usually not saved in RRD DB,
you can activate the option without seeing landslides in the graphs.
