The new attribute <volume ... filesystem_check="true|false"/>
allows to change the default value for the fs_passno field in
the generated fstab file. By default kiwi sets "0" in this
field and leaves it up to the user to customize this as
appropriate via script code. Coding changes to the fstab file
via scripts are not very user friendly and with respect that
systemd takes over control and generates checkers depending on
the value of fs_passno it would be good if there is a way to
explicitly specify if checks to the filesystem are wanted or
not. Therefore the new attribute now exists. If set to: true
this results in a value of "2" for the fs_passno field. Please
note the root/boot and efi entries are excluded from this
setup. This Fixes#1728
