This fixes `fetchurl-force.nix` not being installed, which breaks
bundix for some gems.
E.g.
```
$ nix-build --argstr url https://rubygems.org/gems/nio4r-2.1.0.gem /nix/store/y6959dxal86l3alc0ryf7752prbbkzxg-bundix-2.2.0/lib/ruby/gems/2.3.0/gems/bundix-2.2.0/lib/bundix/fetchurl-force.nix
error: getting status of ‘/nix/store/y6959dxal86l3alc0ryf7752prbbkzxg-bundix-2.2.0/lib/ruby/gems/2.3.0/gems/bundix-2.2.0/lib/bundix/fetchurl-force.nix’: No such file or directory
```
The rsync binary was previously built without iconv support which is needed
for utf-8 conversions on darwin. Fixes#26864.
Additionally rsync used to be built with bundled versions of zlib and popt
that were outdated. This decreases the size of the rsync binary by ~82KB.
Removing all `config.mpv.*` options will improve readability. MPV has many
configurable options, and using the config approach is prone to confusion and
unnecessary code duplication. If needed, the user can `override` the relevant
variables in the function itself, so no functionality is lost.
Closes issue #26786
The following errors occur when you start Chromium prior to this commit:
[2534:2534:0625/202928.673160:ERROR:gl_implementation.cc(246)] Failed to
load .../libexec/chromium/swiftshader/libGLESv2.so:
../libexec/chromium/swiftshader/libGLESv2.so: cannot open shared object
file: No such file or directory
[2534:2534:0625/202928.674434:ERROR:gpu_child_thread.cc(174)] Exiting
GPU process due to errors during initialization
While in theory we do not strictly need libGLESv2.so, in practice this
means that the GPU process isn't starting up at all which in turn leads
to crawling rendering performance on some sites.
So let's install all shared libraries in swiftshader.
I've tested this with the chromium.stable NixOS VM test and also locally
on my machine and the errors as well as the performance issues are gone.
