[OE-core] [PATCH] archiver: don't require that images are built using RPM to build SRPMs

[Ross Burton]

The requirement for images being built using RPM is too strict to have access to
the RPM functions, simply checking that package_rpm is in PACKAGE_CLASSES is
sufficient.

Also fail if SRPMs are requested but package_rpm isn't enabled, instead of
silently not doing what we were asked.
