[OE-core] [PATCH v3 4/6] toolchain-scripts: pass env to post-relocate

[Martin Kelly]

It's useful for the post-relocate scripts to be able to see the SDK
environment, for example to see the values of CC, CXX etc. in order to
dynamically generate toolchain files.

To enable this, source the SDK environment script prior to calling the
relocate scripts.

v3:
- Source all top-level env setup scripts instead of just one.
