perf symbols: Set symtab_type in dso__load_sym

In certain cases, dso__load requires dso->symbol_type to be set prior to
calling it. With the introduction of symsrc*, the symtab_type is now
stored in a symsrc which is then passed to dso__load_sym().

Change dso__load_sym() to use the symtab_type from them symsrc (setting
dso->symtab_type as well).

Setup for later patch

"perf symbols: Use both runtime and debug images"
