[PATCH] common/config: support f2fs-tools v1.9 and later

[Eric Biggers via Linux-f2fs-devel <linux-f2fs-devel@lists.sourceforge.net>]

Pass the -f option to mkfs.f2fs when it appears to support it.  This is
required by f2fs-tools v1.9 and later in order to format the filesystem
even when an existing filesystem is detected.  But earlier versions did
not accept this option.
