[sestarnix] Write xattrs to O_TMPFILEs under fs_use_xattr

Technically under fs_use_xattr even temporary files (those created
without any entry in the parent directory) should have the security
label persisted to their xattrs.

In practice this should not be visible, since by definition such a
file won't be evicted from the Starnix directory entry cache until
all FDs are closed, at which point it is deleted, so there's no
need to read the label back from the xattr.
