[Libguestfs] [libnbd PATCH 03/20] nbdsh: Check for python-exec2c installations
Platforms that utilise python-exec [0] wrapper scripts (mainly Gentoo) utilise
basenames of python scripts and executables to decide which python
implementation to use for running that particular command. That makes the nbdsh
"hack" in sh/nbdsh.in not work, even if 'exec -a' is supported by sh.
