Fix/macos py2app libsharpyuv#587

py2app doesn't rewrite @rpath load commands, so libwebp's dependency on libsharpyuv (split out since webp 1.3) goes missing from the app bundle and PIL fails to import at launch. Bundle and patch it explicitly, same as the freecell-solver lib.
install_name_tool invalidates py2app's ad-hoc signature, so a bundle patched after signing (e.g. the libsharpyuv fix, or the existing fc-solve rpath fix) gets silently SIGKILLed by macOS on launch. Verified locally: without this, the fixed app dies with no output at all: the patched dylib breaks the code signature seal.

Okay, I'll merge it. @bwrightkc Does this affect the packages on Sourceforge too? Will I need to regenerate those? Or is this just an issue with the build process? |

That DMG also is affected - the build workflow would have to be run again now to take this update I believe? |

Yes, I'll go trigger it. |

Fixes #586
libsharpyuv.0.dylib is not being bundled by py2app or identified as being required by its dependency walker. I'm working on troubleshooting why that is upstream, but this patch will manually copy it in as part of the build process for now.
