cube: Link to Threads directly
On Ubuntu 20.04, it was found that the validation layers fail to launch in vkcube & vkcubepp
due to a missing dependency on libpthread. While newer Ubuntu versions use a glibc version
where libpthread is integrated into libc, older ubuntu's do not so we need to link threads
directly in order for validation layers to be loadable.
