Replace the deprecated one-element arrays with flexible-array members
in the structs filesystem_attribute_info and filesystem_device_info.
There are no binary differences after this conversion.

Changes in v2:
- Take struct size changes into account and do not subtract 2 additional
bytes after feedback from Gustavo A. R. Silva
- Compare the binaries before and after the conversion and add a note
that there are no differences
