Add FAKEROOTNOENV variable

Add a FAKEROOTNOENV which does the opposite of the FAKEROOTENV variable
and is data loaded into the environment for tasks without the fakeroot
flag.

The intent here is to provide a way to control the environment when we
aren't needing fakeroot context which allows us to unload the preload
from memory entirely and gain a valuable speedup.

I'm not 100% happy with needing this at the bitbake level, particularly
with the cache hit but it does give a valuable speedup.
