tests: write-error-msg: avoid false-failure

Browse Source 
* tests/write-error-msg: Do not require that a disk full
diagnostic include additional information. In some cases, there
is no valid errno value, so we cannot provide more information.
This was exposed by a patch that coincidentally caused the length
of grep's help output to be precisely 4096 bytes long.
