[Ada] Fix spurious warning on unreferenced internal generic instance
This patch removes a spurious warning, saying that an internal entity of
a generic formal package is unreferenced. The immediate cause of this
warning is that the internal entity is explicitly flagged as coming from
source.
The explicit flagging was added decades ago to fix a missing
cross-reference in the ALI file. Apparently these days the
cross-references work fine without this flag.
