[LTP] [PATCH v3 4/5] syscalls/quotactl05: add project quota test for xfs filesystem

This is a variant about quotactl02. It is used to test project quota.
I split it into a new case instead of adding it in quotaclt02 because
kernel doesn't permit mount both group and project quota before
commit d892d5864f02 ("xfs: Start using pquotaino from the superblock.").

+ * Test Name: quotactl05
+ *
+ * Description:
+ * This testcase checks basic flags of quotactl(2) for project on an XFS file
+ * system:
+ * 1) quotactl(2) succeeds to turn off xfs quota and get xfs quota off status
+ * for project.
+ * 2) quotactl(2) succeeds to turn on xfs quota and get xfs quota on status
+ * for project.
+ * 3) quotactl(2) succeeds to set and use Q_XGETQUOTA to get xfs disk quota
+ * limits for project.
+ * 4) quotactl(2) succeeds to set and use Q_XGETNEXTQUOTA to get xfs disk
+ * quota limits Cgreater than or equal to ID for project.
+ * 5) quotactl(2) succeeds to turn off xfs quota and get xfs quota off statv
+ * for project.
+ * 6) quotactl(2) succeeds to turn on xfs quota and get xfs quota on statv
+ * for project.
