makefs: ffs: Print all options when debugging

[jlduran]

Summary

Catch up showing all the options in ffs_dump_fsinfo().

Test Plan

makefs -d 0xa00 -t ffs -o version=2,label="hello world" foo.img /tmp

• Make sure that -t ffs appears before -o ..., don't ask me how I know.

Although NetBSD is no longer a direct upstream for makefs(8), an equivalent patch was submitted to NetBSD first, to avoid introducing unnecessary differences between the two code bases (GNATS bin/60285).
