  mapcontext: fix out-of-bounds read on short BoundingBox SRS

The General.BoundingBox.SRS value from a Web Map Context document was
only checked against the "AUTO:" prefix before stripping 5 bytes with
pszValue + 5, so an SRS shorter than the assumed "EPSG:" prefix read
past the end of the value. Strip only when the value starts with
"EPSG:", otherwise pass it through unchanged.
