Clean up sunshine-bin-debug too when falling back to source build

When sunshine-bin trips the ldd check and we switch to the source build,
the prior install left sunshine-bin-debug behind. The source package
includes its own sunshine-debug which collides on
/usr/lib/debug/usr/bin/sunshine.debug, so pacman refuses the install.

Remove both sunshine-bin and sunshine-bin-debug before yay -S sunshine.
uninstall.sh similarly drops all four variants.
