[PATCH 2/5] Replace program_invocation_short_name with prog_name from command line

[Jeevaka Prabu Badrappan]

program_invocation_short_name is global variable provided by glibc.

Inorder to get the igt built for Android(without glibc), replaced the
program_invocation_short_name with the prog_name.
