Get the program name from the name of the executable
This enables us, during the development phase, to install in-development
binaries as "imag-unstable-<command>" (for example), so that we have
"imag" as a release binary in PATH and "imag-unstable" as a development
binary in PATH.
The change also enables the "imag" binary itself (if it is named
"imag-unstable" for example) to call imag-unstable subcommands, because
it calls "<own binary name>-<command>", for example
"imag-unstable-diary" instead of "imag-diary".
