btrfs-progs: document force option in mkfs usage(); add long opt 

I missed updating the mkfs.btrfs usage() when I added the
option to force fs overwrite.

Update that, and while we're at it add a long option, since
all other commands have long counterparts.

Force overwrite when an existing filesystem is detected on the device.
By default, mkfs.btrfs will not write to the device if it suspects that
there is a filesystem or partition table on the device already.
