CorebootPayloadPkg: Remove empty folder reference in DEC file

In current CorebootPayloadPkg.dec an empty 'Include' directory is
listed in [includes] section. However, this empty directory will
not be mirrored into git repo. If the source tree is pulled from git,
the 'Include' empty folder will not exist and it will cause build
failure. The fix is to remove the whole [Includes] section in the
DEC file.
