f6e7ea43c3 http/smtp: Fix wrong character class usage
A call to `extract_filename_from_content_disposition()` is only
efficient if the string is guaranteed to contain the pattern that
is removed by `sub()`. Due to missing brackets around the `[:blank:]`
character class, an overly long string (756kb) ending in
"Type:dtanameaa=" matched the wrong pattern causing `sub()` to
exhibit quadratic runtime. Besides that, we may have potentially
extracted wrong information from a crafted header value.

(cherry picked from commit 6d385b1ca724a10444865e4ad38a58b31a2e2288)
