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.

This should allow us to easily add system-wide Chromium extensions via a
NixOS configuration similar to this:
{ pkgs, ... }: {
environment.pathsToLink = [ "/share/chromium/extensions" ];
environment.systemPackages = [ pkgs.my-shiny-extension ];
}
For more details about what Chromium expects within that directory, see:
https://developer.chrome.com/extensions/external_extensions
I've introduced this because of a personal desire to gain more control
about which extensions are installed and what they are able to do. All
of the extensions I use are free software, but despite that it's useful
to either easily patch them and also prevent unwanted automatic updates.
Tested this using the NixOS "chromium.stable" test on x86_64-linux.

Cc: @offlinehacker because of #21050
somehow, the build seems to have changed with chromium 58, to not auto
download the node binary. It is needed to generate webui files and we
can substitute our own.
