xfstests/common: don't assume sysfs attrs all reside under test dev

Browse Source 
_require_xfs_sysfs() currently assumes that all sysfs attributes reside
under a device-specific subdirectory in the XFS sysfs hierarchy. It is
hardcoded to use the TEST_DEV mount and expect the relative attribute
path as a parameter.

Not all sysfs attributes are associated with specific devices or mount
points, however. Remove the hardcoded device name part of the attribute
path from _require_xfs_sysfs() and let the caller construct the relative
path based on the sysfs XFS root directory.
