Xtensa core configuration must be added to linux before it can be
built for that xtensa CPU variant. Extract configuration files from the
xtensa overlay as is done for other packages that need to be configured
for a specific xtensa core.

Changes v1->v2:
- replace ARCH_XTENSA_CORE_NAME with ARCH_XTENSA_OVERLAY_FILE in overlay
  application conditions in package makefile;
- add ARCH_XTENSA_OVERLAY_URL to EXTRA_DOWNLOADS in package makefile.
