Chunyu Hu a784a3a39c selftests/mm/vm_util: robust write_file()
Add three more checks for buflen and numwritten.  The buflen should be at
least two, that means at least one char and the null-end.  The error case
check is added by checking numwriten < 0 instead of numwritten < 1.  And
the truncate case is checked.  The test will exit if any of these
conditions aren't met.

Additionally, add more print information when a write failure occurs or a
truncated write happens, providing clearer diagnostics.
