[LTP] [PATCH 1/2] lib/tst_mkfs: new tst_mkfs_sized function for create appointed size fs

Hi!

That is true, well the 'man mkfs' is confusing as well since it looks
like the size argument is supported generally by mkfs binaries...

And we should call it extra_opt, since it's just one option.

Having two nearly identical *_mkfs() functions would be confusing as
well. I would have just changed the function prototype and fixed all the
testcases that use it (36 testcases if I'm counting right).
