[PATCH v3 1/2] merge-ll: catch close() errors when writing external tempfiles

When writing out tempfiles for an external merge driver, we catch the
case that write() fails, but not the follow-up close(). This close()
would usually succeed, but the system could report a delayed write error
(e.g., on a network file system).

Since we're adding a new error message here, we'll also make the
existing one match it: mark it for translation and mention the actual
path. The exact wording here was picked to match some existing
translated messages.

Since v2, this is hopefully written in a more obviously-correct way,
rather than the short-circuit OR.
