howto/using-merge-subtree: mention --allow-unrelated-histories

Without passing --allow-unrelated-histories the command sequence
fails as intended since commit e379fdf34fee ("merge: refuse to create
too cool a merge by default"). To setup a subtree merging unrelated
histories is normal, so add the option to the howto document.
