[Libguestfs] [PATCH] Change fallback name for external supermin helper

[Olaf Hering]

Use basename of external helper instead of 'no' for external supermin
helpers. This gives a clear error messages what binary is actually
missing, and it is now possible to install the missing package without
recompiling libguestfs. In addition its now also possible to use private
builds of supermin (if they are in PATH) with a given libguestfs binary
package.
