common: add _require_norecovery

This patch adds checking code whether filesystem supports norecovery
mount option or not.  Use this in the following xfs test.

 xfs/200         (recovery vs ro-block device)

Currently, norecovery mount option is used by xfs only. But some of
log-based filesystems (e.g., f2fs) are able to support it later.
