bitbake: ast: Warn on multiple builtin config fragments for the same variable

Browse Source 
Having multiple builtin config fragments for the same variable
(eg OE_FRAGMENTS = "... machine/A ... machine/B") is not supported.
Warn the user to make them fix this but continue with the normal
variable evaluation : the last affectation "wins".

Added warning looks like:
WARNING: Multiple builtin fragments are enabled for machine via variable OE_FRAGMENTS: machine/qemux86-64 machine/test machine/qemux86-64. This likely points to a mis-configuration in the metadata, as only one of them should be set. The build will use the last value.

(Bitbake rev: 1c12aa23f6678dc289fc0e0d8b4dad311bd39c35)
