[Libguestfs] [PATCH] Chop final '/' in output directory (RHBZ#1146753)

[Pino Toscano]

If the specified output directory ends with a slash, chop it then;
leaving it in will create problems later, like creating the temporary
directory inside the output directory (and not aside it), and trying to
rename it to the directory containing it (which will fail indeed).
