[OpenWrt-Devel] [PATCH fstools] libblkid-tiny: fix f2fs labels by increasing label buffer

f2fs max label length is 1024B (512 * uint16_t) which is way above
current 256B used in `struct blkid_struct_probe` which renders labels on
f2fs system unusable:

 $ mkfs.f2fs -l drive /dev/sda1
 $ block info /dev/sda1
 label buffer too small 1024 > 255

So increase the label buffer again in order to make enough space for
f2fs labels.

Fixes: FS#2735
