Only one callsite of dso__load_sym() uses the want_symtab functionality,
so place the logic at the callsite instead of within dso__load_sym().
This sets us up for removal of want_symtab completely once we keep
multiple elf handles (within symsrc's) around.
Setup for the later patch
"perf symbol: use both runtime and debug images"
