[LTP] [PATCH v1] fs_fill: Increase test loop device size to 1GB

[Wei Gao]

On PPC64 the page size is 64K and this causes trouble on btrfs
filesystems of small size(LTP currently use 300M), the threads
could compete for a very small number of pages/blocks to actually
write the data. So Increase minimal device size to 1G avoid the
corner case.
