aws-kvs: add the aws-kvs package.

The AWS KVS SDK provides functionality to easily stream video from
connected devices to AWS for processing, including ML, playback, and
analytics.

The Morse Micro package adds procd support to manage stream configuration
and triggering the aws stream.

+#File: 002-libcurl_setopts.patch
+#Description: The provided patch addresses an issue stemming from the default libcurl setting, which attempts to resolve the AWS URL to IPv6. This resolution fails, resulting in a 'could not resolve host' error. The patch adjusts the curl option to IPv4, effectively resolving the host successfully.
