    gen-lockedsig-cache: ensure symlinks are dereferenced
    
    If you set up a local mirror in SSTATE_MIRRORS then you can end up with
    symlinks in SSTATE_DIR rather than real files. We don't want these
    symlinks in the sstate-cache prodcued by gen-lockedsig-cache, so
    dereference any symlinks before copying.
