[Build] Old Style Casts

[shinra-electric]

When building directly from the RPCS3 repository, compilation will fail with many old-style-cast errors.

This is a known issue and is being tracked here.

The workaround is to suppress these warnings, but a proper fix is required.

Currently the script will pull from my own RPCS3 fork, pull updates from the upstream branch, and apply the workaround.

In the short term, I plan to at least inject the workarounds using the script, so it will work directly from the official RPCS3 repo and my fork won't be required anymore.

Update:
Currently the script will apply the workaround to suppress the warnings into the source code. An upstream fix for the underlying issue is still preferred.

This has been fixed in the master branch.
