libevhtp: update to 1.2.18, add maintainer

Versions earlier than 1.2.15 had security vulnerabilities, especially
related to the bundled oniguruma.  Now libevhtp uses a system-provided
library instead.  The API changed as well, requiring patches to
seafile-server.

Adds @cotequeiroz Eneas U de Queiroz as maintainer.
