Raise minimum supported dosfstools to 3.0.18
From the commit message:
This earlier commit [1] from 2013 recognised the new names for programs
in dosfstools >= 3.0.18, specifically mkfs.fat and fsck.fat. Now that
the oldest supported distributions use dosfstools >= 3.0.18 it is no
longer necessary to support using the old names of mkdosfs and dosfsck,
so remove that code.
