sbtoelf: implement sb extraction for sb1
Load, fill and call/jump instructions are extracted as elf files like for sb2. Because of the size limitations of the sb1 instructions, the resulting elf files can easily have hundreds of sections. The (currently) implemented elf simplification method will hopefully reduce this to a few sections only Change-Id: I8fd6ed935ac3128f244bbd71c782e2a0a1c6d44a
