icecc-create-env: Use program interpreter for deps
ldd cannot always be used to determine a program's dependencies correctly, particularly when the program specifies an alternate program interpreter (dynamic loader). This commonly happens when using a uninative tarball. Instead, determine the program's requested interpreter, and ask it to list the dependencies.
