The helper is used to test if a specific filesystem feature can
be enabled. Currently only implemented testing overlayfs features.
Overalyfs features (e.g. redirect_dir, index) are configurable from
Kconfig (the build default), by module parameter (the system default)
and per mount using the mount option ${feature}=[on|off].
The helper is going to be used by overlay tests, which depend
on the inodes index feature.
