util-linux: Disable minix support.

util-linux: Disable minix support.

Disable building of {mkfs,fsck}.minix, which are used
to support minix file-systems.  Minix predates Linux and
support for its file-systems is unlikely to be needed.

No recipes otherwise reference minix, except in patches
to autotools configuration scripts, so there should be no
impact to other recipes.
