gnu: libtorrent-rasterbar: Update to 2.0.9.

Update the package.  Since other packages do depend on the previous
version (and according to their documentation do recommend it), the previous
version is exposed as libtorrent-rasterbar-1.2.

The v2.0.9 requires patching to get tests working.  Sadly one of the changes
is to introduce new binary file, so it is fetched as an input and applied in a
phase.  Snippet is used instead to do the rest of the patching.

* gnu/packages/bittorrent.scm (libtorrent-rasterbar)[version]: Update to
2.0.9.
[source]<snippet>: Patch test/test_copy_file.cpp.
[native-inputs]: Add the missing file (v2_empty_file.torrent).
[arguments]<#:phases>: And add a phase copying it into the correct place.
* gnu/packages/bittorrent.scm (libtorrent-rasterbar-1.2): New variable.
(qbittorrent)[inputs]: Use libtorrent-rasterbar-1.2.
* gnu/packages/enlightenment.scm (epour)[inputs]: Use
libtorrent-rasterbar-1.2.
