Alter copr spec file for Fedora 41 and Rawhide

[loops]

SlouchyButton mentioned in #6015 that a Fedora Openssl packaging change was likely causing a problem for the copr build.

The deprecated engine header has been broken out into its own package. Add a dependency on it for Fedora 41 and Rawhide.

Just a note here, this might stop working in future Fedora versions as the use is deprecated. Ideally, the OpenSSL engine should not be used, but since wezterm is not using it directly afaik, there is a chance that newer versions of the dependency that does use it will fix it before it becomes a problem.

Otherwise, this looks good, slight problem is that when I tried to mockbuild the new spec file it seems that time dependency fails to build, possibly due to newer rust.

   = note: this is an inference error on crate `time` caused by an API change in Rust 1.80.0; update `time` to version `>=0.3.35` by calling `cargo update`

This shouldn't really block this PR as it is unrelated, but will also need further investigation to fix.
