[analyzer] MallocSizeofChecker false positive: when sizeof is argument

to addition.

We should not to warn in case the malloc size argument is an
addition containing 'sizeof' operator - it is common to use the pattern
to pack values of different sizes into a buffer. 

Ex:

uint8_t *buffer = (uint8_t*)malloc(dataSize + sizeof(length));
