[OE-core] [PATCH 6/6] package_rpm: Allow translation of requirement to package name

[Mark Hatle]

In the translate oe to smart function, we only translated package names.
However, it's allowed that people can put in a dependency name in the
IMAGE_INSTALL.  So on a failure to translate a package name, we fall back
and attempt to resolve based on a package's provide.

Note: it may be possible to generate an unsolvable install solution.  If the
dependency is provided by one or more things that conflict with something else
set to be installed.  We can't determine this until smart is run.

If this occurs, file a bug and we'll have to identify a way to deal with the
RCONFLICTS and RREPLACES.  As a workaround replace the conflict REQUIRES with
actual package names.
