[Buildroot] [git commit branch/2020.02.x] package/dovecot: security bump version to 2.3.11.3

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=1ef350aa6e3b19a723f8485980a8d0bba7a70dc6
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2020.02.x

Release notes:
https://dovecot.org/pipermail/dovecot-news/2020-August/000440.html

Fixes the following CVEs:

* CVE-2020-12100: Parsing mails with a large number of MIME parts could
  have resulted in excessive CPU usage or a crash due to running out of
  stack memory.
* CVE-2020-12673: Dovecot's NTLM implementation does not correctly check
  message buffer size, which leads to reading past allocation which can
  lead to crash.
* CVE-2020-10967: lmtp/submission: Issuing the RCPT command with an
  address that has the empty quoted string as local-part causes the lmtp
  service to crash.
* CVE-2020-12674: Dovecot's RPA mechanism implementation accepts
  zero-length message, which leads to assert-crash later on.
