Subject: [PATCH v3 2/3] perf scripts python: arm-cs-trace-disasm.py: set start vm addr of exectable file to 0

For exectable ELF file, which e_type is ET_EXEC, dso start address is a
absolute address other than offset. Just set vm_start to zero when dso
start is 0x400000, which means it is a exectable file.
