Andrew Kaster 6fff03713c Ladybird: Ensure that installed ladybird can launch WebContent process
Always call platform_init after there's a QApplication, because in the
installed configuration that's how we find the resources.

Try QCoreApplication::applicationDirPath() after looking in ./WebContent
for the WebContent process. In an installed configuration, ladybird and
WebContent will both be in $PREFIX/bin.

Add install rules for WebContent and its linked libraries, for if they
ever differ from ladybird's.
