[OE-core] [PATCH 1/1] package_manager.py: fix rpm based do_rootfs failed while IMAGE_INSTALL_append = " python3"

[Hongxu Jia]

While a pkg name (such as python3) not existed in variable
PACKAGES, but provided by another pkg (such as python-core),
in this situation, rpm based do_rootfs could not search it in
the feeds.

The fix is to invoke 'smart query --provides' to do the search
if the feeds search failed. We don't drop the feeds search,
because the smart query search is too slow, and the feeds
search is fast and could work well with most pkgs.
