perf symbols: Factor want_symtab out of dso__load_sym()

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 symbols: Use both runtime and debug images"
