prepare-root: Properly check return value of snprintf()

When the target buffer is to small to hold the resulting string a value
larger or equal than the buffer's size is returned. (In pre C99
versions, snprintf returned -1 in this case, too.)

So to ensure that no truncated paths are used adapt the error checking
accordingly.
