[OE-core] [PATCH] linux-yocto-dev: Dynamic SRCREV update

[Darren Hart]

The current implementation would result in the default SRCREVs being
used by the fetcher, even though the anonymous python would update them
to AUTOREV. This appears to be something to do with early parsing
bitbake black magic.

This patch ensures the default is never assigned if we are actually
building the recipe by using a function to assign it in the first place.

The USE_DEFAULT* variables are removed as they are not necessary to
allow for overriding the SRCREVs.

The anonymous python parse check is moved closer to the top of the
recipe to be a bit more logically representative of its intended
purpose.
