Thomas Quinot cd1832fe92 Reorganize the handling all-zeroes terminal block in sparse mode

The intent of the previous code in that case was to force
an explicit write, but the implementation was incorrect, and
as a result the write was never performed. This new implementation
instead uses ftruncate(2) to extend the file with a trailing hole.

Also introduce regression tests for these cases.
