[Bug-wget] [PATCH 6/8] Add extern declaration for program_arsgstring

[Darshit Shah]

In test.c, this patch changes the type of program_argstring to char *
from a const char *. This is because, we use a char * string in the rest
of the program and declare an extern accordingly. Removing the const
type helps in keeping the code cleaner at no extra cost.
