Basic tests for getxattr(2) and make sure getxattr(2) handles error
conditions correctly.
There are 4 test cases:
1. Get an non-existing attribute,
getxattr(2) should return -1 and set errno to ENOATTR
2. Buffer size is smaller than attribute value size,
getxattr(2) should return -1 and set errno to ERANGE
3. Get attribute, getxattr(2) should succeed
4. Verify the attribute got by getxattr(2) is same as the value we set
