LU-8817 tests: Update 'min_ost_size'

On setup where MDS and client are on same node
lctl get_param osc.*.kbytesavail returns the
value from OSP. This patch updates function
min_ost_size to use "lfs df" output instead of
reading it from proc.

Output of 'lfs df'. 'Available' field only.
$ lfs df | grep OST | awk '{print $4}' | sort -n | head -n1
151276

Output with current code:
$ lctl get_param -n osc.*.kbytesavail | sort -n | head -n1
151004
