    uml: define "generic" subtarget
    
    UML didn't have a subtarget defined.
    
    While this compiled fine, the patch caused funny filenames
    for the generated files to appear:
     - "openwrt-uml--vmlinux"
     - "openwrt-uml--squashfs.img"
     - "openwrt-uml--ext4.img"
     - ...
    
    since "generic" is implied anyway, let's just set it.
    
    Fixes: d997477775bf ("treewide: remove implicit SUBTARGET")
