Basic tests for setxattr(2) and make sure setxattr(2) handles error
conditions correctly.

There are 7 test cases:
1. Any other flags being set except XATTR_CREATE and XATTR_REPLACE,
   setxattr(2) should return -1 and set errno to EINVAL
2. With XATTR_REPLACE flag set but the attribute does not exist,
   setxattr(2) should return -1 and set errno to ENOATTR
3. Create new attr with name length greater than XATTR_NAME_MAX(255)
   setxattr(2) should return -1 and set errno to ERANGE
4. Create new attr whose value length is greater than XATTR_SIZE_MAX(65536)
   setxattr(2) should return -1 and set errno to E2BIG
5. Create new attr whose value length is zero,
   setxattr(2) should succeed
6. Replace the attr value without XATTR_REPLACE flag being set,
   setxattr(2) should return -1 and set errno to EEXIST
7. Replace attr value with XATTR_REPLACE flag being set,
   setxattr(2) should succeed

 V2:
	1. Statically initialize test case array
	2. Use TTERRNO with TPASS and TFAIL to print TEST_ERRNO message
