In the user.* namespace, only regular files and directories can
have extended attributes. Otherwise setxattr(2) should return -1
and set errno to EPERM.
There are 7 test cases:
1. Set attribute to a regular file, setxattr(2) should succeed
2. Set attribute to a directory, setxattr(2) should succeed
3. Set attribute to a symlink which points to the regular file,
setxattr(2) should return -1 and set errno to EEXIST
4. Set attribute to a FIFO, setxattr(2) should return -1 and set
errno to EPERM
5. Set attribute to a char special file, setxattr(2) should
return -1 and set errno to EPERM
6. Set attribute to a block special file, setxattr(2) should
return -1 and set errno to EPERM
7. Set attribute to a UNIX domain socket, setxattr(2) should
return -1 and set errno to EPERM
