Subject: SCI32: Fix PHANT1 save file interoperability

Phantasmagoria 1 save files are uncompressed because they are small
and interoperable with the original interpreter, but the game scripts
frequently rename them. Renaming save files unconditionally compresses
the result and so only some files have been interoperable.

Phantasmagoria 1 files now remain uncompressed when renamed.
