Starting from util-linux v2.23 fstrim(1) reports trimmed bytes
differently, e.g.
new fstrim: /mnt/ext4: 9.7 GiB (10411118592 bytes) trimmed
old fstrim: /mnt/ext4: 10411118592 bytes were trimmed
generic/260 reports syntax error
+./tests/generic/260: line 111: [: 9.7: integer expression expected
+./tests/generic/260: line 121: [: 9.7: integer expression expected
+./tests/generic/260: line 183: [: 9.7: integer expression expected
Add a new filter called _filter_fstrim in common/filter and get the
correct trimmed bytes in generic/260, so the test passes with both old
and new fstrim.
