librespeed-cli-rust: add new package

Rust port of librespeed-cli for 32-bit PowerPC targets not supported by
the Go implementation, such as CZ.NIC Turris 1.x.

The CLI output of --list and --csv-header matches the Go client, so it
can be used as a drop-in replacement. Both implementations install
/usr/bin/librespeed-cli and therefore PROVIDES/CONFLICTS are set
accordingly.

Use libopenssl instead of rustls' ring backend, which has significantly
better AES-GCM performance on big-endian PowerPC.

+  LibreSpeed client for measuring internet speed from command line.
+
+  This is a Rust port of librespeed/speedtest-cli. The original is written
+  in Go, whose toolchain targets only ppc64 and ppc64le, so librespeed-cli
+  is unavailable on 32-bit PowerPC devices. Both packages install
+  /usr/bin/librespeed-cli, hence the conflict.
+endef
+
+# rustls' default crypto backend, ring, does build here, but it has no assembly
+# for big-endian PowerPC and falls back to its portable C: on mpc85xx its
+# AES-GCM measured under half of libopenssl's throughput. libopenssl is in the
+# image anyway, so linking against it is both faster and one TLS stack fewer.
