qtshadertools cross-compile needs the host 'qsb' (Qt Shader Builder)
tool, just like qtbase needs host moc/rcc/uic. Added a native cmake
build step that compiles qsb from the 6.11.1 source and installs it
into the shared qt-host-build prefix.
Also regenerate pam-redbear Cargo.lock (stale after 0.2.5 version bump
of redbear-login-protocol path dependency).
