[PATCH 2/2] common/quota: adapt _require_prjquota() for f2fs

[Chao Yu <yuchao0@huawei.com>]

In _require_prjquota(), let's check project quota support as below for
f2fs:
- For image support, check 'project_quota' on enabled feature list of
specified device.
- For kernel support, check /sys/fs/f2fs/features/project_quota sysfs
entry status.
