btrfs: Add test to check if shrink works well with fstrim

There is a bug in trim code which leads to fstrim accessing beyond
device boundary.

The test case will check if fstrim, then shrink, then fstrim, all of
them works without problem.

The fix is titled "btrfs: trim: fix underflow in trim length to prevent
access beyond device boundary".
