python-smartpm: report warn rather than error during install with --attempt
With the following config and build image:
...
IMAGE_INSTALL_append = "shadow man-pages"
EXTRA_IMAGE_FEATURES += "doc-pkgs"
...
There is an error during install with --attempt, and it breaks the build.
...
|error: file /usr/share/man/man5/passwd.5 from install of
shadow-doc-4.2.1-r0.i586 conflicts with file from package
man-pages-3.71-r0.i586
...
For complementary and 'attemptonly' package processing, we should make sure
the warn rather than error messages reported.
