[OE-core] [PATCH 1/2] toolchain-scripts.bbclass: Allow sourcing of subscript for environment

[Otavio Salvador]

Sometimes we require extra environment settings to be available on the
environment for proper SDK work. This were done, in past, using
'_append' tasks however with the split of the environment in a
canadian package this has been broken.

The easier and more flexible solution is to use environment subscripts
which are sources by the main script. These are now looked at:

 $OECORE_NATIVE_SYSROOT/environment-setup.d/*.sh

and sourced.
