toolchain-scripts.bbclass: Allow sourcing of subscript for environment
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.
