DWARF reading: fix getting of `DW_AT_declaration` flag

According to the DWARF standard, not all attributes of the debugging
information entry referenced by a DW_AT_specification attribute apply to the
referring debugging information entry. For example, DW_AT_declaration cannot
apply to a referring entry.

Add function `GetDirectAttribute`, which uses `dwarf_attr` instead of
`dwarf_attr_integrate`, and use it in `GetFlag` in case of getting
the `DW_AT_declaration` flag.
