 Summary of the bug:
 How to reproduce:
 {{{
 % ffmpeg -v debug -seekable 0 -icy 0 -f hls -i 'https://path-to-
 hls.host/manifest' test.mp4
 ffmpeg version 4.4.2-0ubuntu0.22.04.1 Copyright (c) 2000-2021 the FFmpeg
 developers

 ...

 [https @ 0x5b494dcf0700] request: GET /manifest HTTP/1.1
 Accept: */*
 Connection: close

 ...

 [https @ 0x5b494dcfbf00] request: GET /key HTTP/1.1
 Accept: */*
 Range: bytes=0-

 }}}

 The manifest itself does obey -seekable 0 and not sent with range header.
 But the key file always send with range header no matter you set it as
 seekable or not and also there is no other way to disable range header.
