Make poky-qemu and related scripts work with arbitrary SDK locations

* No longer assume SDK toolchains are installed in /opt/poky
* [BUGFIX #568] where specifying paths to both the kernel and fs
  image caused an error due to POKY_NATIVE_SYSROOT never being
  set, triggering failure of poky-qemu-ifup/ifdown
* Cosmetic improvements to usage() functions by using basename
