The _set/_get/_has/_require_fs_sysfs_attr helpers all operate on
per-device sysfs entries under /sys/fs/$FSTYP/$dev. Insert "_dev_"
into their names to distinguish them from other sysfs paths such as
/sys/fs/$FSTYP/features/, and update all callers. No functional
change.

There is heavy overlap between _require_fs_sysfs and
_require_fs_sysfs_dev_attr, and their ambiguous names make it
difficult to tell them apart.
Make _require_fs_sysfs_dev_attr a generic helper that requires both
a device and an attribute, remove _has_fs_sysfs and _require_fs_sysfs,
and add _require_test_sysfs_dev_attr and _require_scratch_sysfs_dev_attr
wrappers.

The sysfs policy helpers in common/sysfs are only usable for btrfs.
The only filesystem supported by them is btrfs and the only callers
are btrfs tests. So rename them with a _btrfs_ infix and move them to
common/btrfs, then remove empty common/sysfs and its references.

More and more test cases depend on /sys/fs/$FSTYP/features/ entries.
To improve code structure and maintainability, introduce the
- _has_fs_sysfs_feature_attr
- _get_fs_sysfs_feature_attr
- _require_fs_sysfs_feature_attr
helpers.

Switch from btrfs specific helpers to the generic sysfs helpers
across btrfs test cases, reduce code duplication.
