libmakepkg/tidy: fix debug sources not being properly detected sometimes
DW_AT_comp_dir is meant to contain the directory in which the compiler
was run
DW_AT_name contains the source file the compiler was told to use.
In the event that DW_AT_name is an absolute path, it is (obviously) not
meant to be computed relative to DW_AT_comp_dir. However, we did not
handle this correctly, and as a result tried to copy source files using
doubled-up filepaths.
The correct approach should be to use DW_AT_name on its own, in the
event that it is an absolute path.
See http://wiki.dwarfstd.org/index.php?title=Best_Practices.
This fixes debug package generation for many packages that use absolute
paths in their build systems... like CMake.
