When the debug info refers to a dwo with relative `DW_AT_comp_dir` and `DW_AT_dwo_name`, we only print the `DW_AT_comp_dir` in our error message if we can't find it. This often isn't very helpful, especially when the `DW_AT_comp_dir` is ".": ``` (lldb) fr v error: unable to locate .dwo debug file "." for skeleton DIE 0x000000000000003c ``` I'm updating the error message to include both `DW_AT_comp_dir` (if it exists) and `DW_AT_dwo_name` when the `DW_AT_dwo_name` is relative. The behavior when `DW_AT_dwo_name` is absolute should be the same.
