[LTP] [PATCH v3] Use real FS block size in fallocate05

[Jan Stancek]

----- Original Message -----
> fallocate() behavior depends on whether the file range is aligned to full
> blocks. Make sure that the test always uses aligned file range so that
> the test is consistent across platforms.
> 
> Also use the TEST() macro to prevent errno pollution and increase test device
> size to avoid weird edge cases that don't happen in the real world.
