Peter Kjellerstedt 16fb9b80e3 oe-init-build-env*: Allow $OEROOT to be predefined

The current implementation of oe-init-build-env and
oe-init-build-env-memres requires that they are sourced from the
directory that will be known as $OEROOT. This makes it hard to write a
wrapper script with the same name as the original OE script which,
e.g., sources the original OE script from a sub-directory.

With this change, $OEROOT can be predefined when oe-init-build-env or
oe-init-build-env-memres is sourced, allowing the original OE scripts
to be anywhere.

Normally this is called as '. ./oe-init-build-env builddir '

This works in most shells (not dash), but not all of them pass arg1 when

being sourced. To workaround the shell limitation use "set arg1" prior

to sourcing this script.
