conf/bitbake.conf package.bbclass: fix dbg package not contain sources while -fdebug-prefix-map used
Tweak DEBUG_FLAGS to use "/usr/src/debug/${PN}/${EXTENDPE}${PV}-${PR}"
as source target path in DWARF. While use gdb to debug binary, it could
work with sources in dbg package.
While -fdebug-prefix-map is used for compiling, we do not need invoking
debugedit to edit DWARF at do_package time, but list where sources files
are.
The copydebugsources uses the list to copy sources to dbg package. It
works whether -fdebug-prefix-map used or not.
