opkg-testing with PROVIDES = "opkg" won't work well for runtime dependencies
(even if you add RPROVIDES unless something will explicitly pull
opkg-testing into the image - VIRTUAL-RUNTIME vars...)

I would name the recipe opkg_git.bb with PV corresponding to real
version based on SRCREV e.g. "1.9+git${SRCPV}".

with
BBFILE_PRIORITY = "4"
and
PREFERRED_VERSION_opkg = "1.9+git%"
it should work as expected

This should be discussed on oe-core ML rather then yocto ML.
