Copy the null byte too in this copy operation to avoid the following
warning:

| libflash/libffs.c: In function 'ffs_part_info':
| libflash/libffs.c:525:3: error: 'strncpy' output may be truncated copying 15 bytes from a string of length 15 [-Werror=stringop-truncation]
|    strncpy(n, ent->name, FFS_PART_NAME_MAX);
|    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
