python-smartpm: really ignore conflicts during install with --attempt

The original patch added in OE-Core commit
bdf07b1698d228dc7ff555199a269b1ff8ceca19 was supposed to ignore
conflicts, but it was unable to do so because it wasn't raising errors
in the right place. When the --attempt option is used (as is done in
complementary package installation for RPM), raise errors immediately
on conflicts, catch errors at the right point so that requested packages
and their dependencies can be ignored, and print appropriate warnings
when doing so.

Fixes [YOCTO #5313].

+Subject: [PATCH] Add mechanism to attempt install without failing
 
-For complementary and 'attemptonly' packages, we need a way to instruct smart to
-try to install, but ignore any failures.
+In OpenEmbedded, for complementary and 'attemptonly' package processing,
+we need a way to instruct smart to try to install, but ignore any
+failures (usually conflicts).
 
 This option only works for the install operation.
