mm/tunable: add a new testcase min_free_kbytes
The tune is used to control free memory, and system always
reserve > min_free_kbytes memory at least.
Since the tune is not too large or too little, which will
lead to the system hang, so I choose two cases, and test them
on all overcommit_memory policy (0, 1, 2), at the same time,
compare the current free memory with the tunable value
repeatedly.
a) default min_free_kbytes with all overcommit memory policy
b) half of mem_free with all overcommit memory policy
