SCUMM: Fix Sophia speaking with Indy's voice when looking at him

When playing as Sophia in some scenes (such as in the Azores), using the
`Look at` verb on Indy would make her speak with Indy's voice, because
the script triggering this sentence for this verb didn't check or
include a line for the case when VAR_EGO is Sophia.

Fortunately, a different script does have this exact same line dubbed
for Sophia, so we can reuse it, as long as the audio offsets have the
values that we expect (and I'm only aware of a single MONSTER.SOU file
for this title, always in English and identical on all ports).
