Variable to determine return type base value

This function is used by the nd_syscall tapset, and returns a string. Set format equal to 1 for a decimal, 2 for hex, 3 for octal.

Note that this function should only be used in dwarfless probes (i.e. 'kprobe.function(“foo”)'). Other probes should use return_str.
