[OE-core] [meta-oe][PATCH] package.bbclass: provide debug sources in externalsrc -dbg packages

[Vignesh Rajendran]

The recipes which are using externalsrc method doesn't contain the
debug sources in their -dbg packages.

Add a handling in copydebugsources function to copy the debugsources for
externalsrc -dbg packages.
