[bug#61445] [PATCH] gnu: qbittorrent: Update to 4.5.0.

[Hilton Chain]

In configure phase:
--8<---------------cut here---------------start------------->8---
checking for libtorrent-rasterbar >= 2.0.8... no
checking for libtorrent-rasterbar >= 1.2.18 libtorrent-rasterbar < 2... no
configure: error: Package requirements (libtorrent-rasterbar >= 1.2.18 
libtorrent-rasterbar < 2) were not met:

Requested 'libtorrent-rasterbar >= 1.2.18' but version of libtorrent is 1.2.15
--8<---------------cut here---------------end--------------->8---

The current libtorrent-rasterbar in Guix is 1.2.18, so guix older than the
update was used for the build.

Resending patches might solve it, I'll have a try.
