scripts/oe-setup-builddir: make environment variable the highest priority source for TEMPLATECONF

This sets the following order:

1. TEMPLATECONF set in the unix environment (for example as a
prefix to '. oe-init-build-env').

2. If empty then $BUILDDIR/conf/templateconf.cfg

3. If absent then $OEROOT/.templateconf (oe-init-build-env sets OEROOT
to where it is, which is poky or oe-core).

I believe this is more logical and consistent with common practice;
it also avoids situations where the user is stuck with cryptic
errors because templateconf.cfg contains something invalid and
that something cannot be overridden from command line.

(From OE-Core rev: 7296c42b8c58e6e08f4210eb7b51d852b1ee950e)
