[OE-core] [PATCH] Nothing uses USERNAME, remove it - can cause sstate-cache conflicts

[Matthew McClintock]

USER is the correct variable to use, also this can affect sstate
cache as well.

I'm not 100% sure about this one but it seems like nothing is using this
variable?

Also one of my build machines (Jenkins specifically) was exporting
USERNAME=root for some reason to the build environment. This was preventing
sstate-cache from being used on other machines where it was not even
defined/used AFAICT
