unix: add missing xattr symlink syscall functions on Linux

Add support for the lgetxattr, llistxattr, lremovexattr and lsetxattr on
Linux, akin to the already existing getxattr, listxattr, removexattr and
setxattr syscalls.

These variants are identical to the already existing variants. except in
the case of a symbolic link where the extended attribute operation is
applied to the link itself rather than to the file that it refers to.
See:

  http://man7.org/linux/man-pages/man2/getxattr.2.html
  http://man7.org/linux/man-pages/man2/listxattr.2.html
  http://man7.org/linux/man-pages/man2/removexattr.2.html
  http://man7.org/linux/man-pages/man2/setxattr.2.html
