LocalSocketTest.testAccessors: fix the *SendBufferSize* test

If one sets a *SendBufferSize* value which is less than
(2048 + SKB_DATA_ALIGN(sizeof(struct sk_buff))) then the value
retrieved will be (2 * (2048 + SKB_DATA_ALIGN(sizeof(struct sk_buff)))).
Otherwise, the value will be doubled.
Modify the test to consider both cases.
