Add a test to check basic functionallity of file_getattr() and
file_setattr() syscalls. These syscalls are used to get/set filesystem
inode attributes (think of FS_IOC_SETFSXATTR ioctl()). The difference
from ioctl() is that these syscalls use *at() semantics and can be
called on any file without opening it, including special ones.
For XFS, with the use of these syscalls, xfs_quota now can
manipulate quota on special files such as sockets. Add a test to
check that special files are counted, which wasn't true before.
