Thomas Guillemard c2c765b30f hbabi: Implement argv (#272)
This commit implements the argv config key in Ryujinx (by creating a temporary copy of the homebrew executable in the sdmc VFS) to make it possible
to load libnx's "romfs" files.

This commit also call Os.Dispose in Ns.OnFinish to dispose all resources when exiting
