Fix moving source files into debug packages

Commit 8bec63bf92d8dd028aa88dbd5109c314cdb9ebea attempted to switch to
using -fdebug-prefix-map to set file locations in debug packages.  It
make a few mistakes...

1) Adding debug C{,XX}FLAGS only worked if DBGSRCDIR was defined in
makepkg.conf.  Fix this by falling back to the default value.

2) Using -fdebug-prefix-map altered a lot of assumptions about file
locations when copying source files into debug packages. This resulted
in lots of messages of failed cp in packaging output.
