mail/fetchmail, fetchmailconf: update to 6.4.3-rc2 (bug fixes)

Add a patch to document --sslproto tls1.3+ and tls1.3 through the manpage,
which hasn't made 6.4.3-rc2 but works since 6.4.0 assuming that the SSL library
supports TLSv1.3.

Remove fetchmailconf patch that is now part of the upstream code.

Switch to .lz downloads, a tiny bit smaller.

Upstream changelog:
## BUGFIXES:
* Plug memory leaks when parts of the configuration (defaults, rcfile, command
  line) override one another.
* fetchmail terminated the placeholder command string too late and included
  garbage from the heap at the end of the string. Workaround: don't use place-
  holders %h or %p in the --plugin string. Bug added in 6.4.0 when merging
  Gitlab merge request !5 in order to fix an input buffer overrun.
  Faulty commit 418cda65f752e367fa663fd13884a45fcbc39ddd.
  Reported by Stefan Thurner, Gitlab issue #16.
* Fetchmail now checks for errors when trying to read the .idfile,
  Gitlab issue #3.

## CHANGES:
* Fetchmail documentation was updated to require OpenSSL 1.1.1.
  OpenSSL 1.0.2 reached End Of Life status at the end of the year 2019.
  Fetchmail will tolerate, but warn about, 1.0.2 for now on the assumption that
  distributors backport security fixes as the need arises.
  Fetchmail will also warn if another SSL library that is API-compatible
  with OpenSSL lacks TLS v1.3 support.
* If the trust anchor is missing, fetchmail refers the user to README.SSL.
