common/quota: Make project quota handling work for ext2 & ext3

Project quota can work for ext2 & ext3 the same way as for ext4.
Handle them properly as currently the tests just fail because of
unknown prjquota mount option. After this patch, tests will be "not
run" because ext4 driver refuses to use project quota mount options
for "old" fs types.
