perf symbols: Fix symbol annotation for relocated kernel
Kernel maps map memory addresses to file offsets.
For symbol annotation, objdump needs the object VMA addresses. For an
unrelocated kernel, that is the same as the memory address.
The addresses passed to objdump for symbol annotation did not take into
account kernel relocation.
This patch fixes that.
