From: Johannes Schindelin <redacted>

When uploading messages via libcurl, `curl_append_msgs_to_imap()`
accumulates each one in a strbuf that grows across loop iterations but
is never released before the function returns.

Release it alongside the existing libcurl cleanup.

Reported by Coverity as CID 1671507 ("Resource leak").
