Subject: [PATCH] Attach the deprecation version to the deprecating call

`export_uses()` wrote `deprecation_version` to `$out['functions'][0]`, the
first recorded function use, instead of the `_deprecated_*()` call that
carries the version. That only looked correct when the deprecating call
happened to be the first call in the scope, as it is in a deprecated file;
whenever another call precedes it, the version was attached to that
unrelated call and the deprecating call got none.

Build the use record first and attach the version to it before appending.

Found during the review of #262 and extracted here as a standalone change.
