Add brackets in SFileSetFilePointer when pointer < 0

This addresses a bug introduced in:

- fe652fe4a6e02041194a0f1b29a0086bd99fb14d

Brackets were not properly included, causing `SFILE_INVALID_POS` to be
returned whenever `DeltaPos` was less than zero, instead of only when
the resulting position was negative.
