test: force mkfs.btrfs to overwrite any existing file systems

Browse Source 
mkfs.btrfs (unlike mkfs.ext4) checks if the target already contains
a file system and refuses to continue if so. This causes spurious fails
in case the random garbage on the temporary device matches a valid FS
header:

[   19.723806] testsuite-64.sh[355]: + udevadm lock --device=/dev/mapper/encbtrfs0 --device=/dev/mapper/encbtrfs1 --device=/dev/mapper/encbtrfs2 --device=/dev/mapper/encbtrfs3 mkfs.btrfs -M -d raid1 -m raid1 -L btrfs_mencdisk -U deadbeef-dead-dead-beef-000000000003 /dev/mapper/encbtrfs0 /dev/mapper/encbtrfs1 /dev/mapper/encbtrfs2 /dev/mapper/encbtrfs3

[   19.920490] testsuite-64.sh[2494]: ERROR: use the -f option to force overwrite of /dev/mapper/encbtrfs0

Let's force mkfs.btrfs to overwrite the file system in such case.
