perf symbols: Ignore ABS symbols when loading data maps
When loading symbols in a data mapping, ABS symbols (which has a value
of SHN_ABS in its st_shndx) failed at elf_getscn(). And it marks the
loading as a failure so already loaded symbols cannot be fixed up.
I'm not sure what should be done. Just ignore them for now. :)
