ShareableGainMap::applyGainMapToBaseImage passes a null value to a
kCFTypeDictionaryValueCallBacks dictionary

Reviewed by Dan Glastonbury.
applyGainMapOptions is created with kCFTypeDictionaryValueCallBacks,
whose retain/release callbacks are CFRetain/CFRelease. When
m_colorSpace was empty, CFDictionarySetValue() was called with a
null value for kCGImageAuxiliaryDataInfoColorSpace, causing
CFDictionarySetValue() to invoke CFRetain(NULL), which is invalid.
Only set the key when m_colorSpace is present.
