bug#67545: wrap-program gives different argv[0] for Python scripts

[Rikard Nordgren]

For example the meld package is using wrap-program and the name of the
actual meld executable will be .meld-real. The idea is that the -a
option to exec in the wrapper script should change the name of argv[0],
but for Python scripts this doesn't work. This means that when doing
"meld --version" it gives ".meld-real 3.22.0" instead of the expected
"meld 3.22.0". Any ideas on how this could be fixed?
