[Libguestfs] [PATCH] build: remove unused gnulib modules



Remove gnulib modules that provide stuff clearly not used within
libguestfs (library, daemon, and C tools).  Among directly and
indirectly modules used previous (and now no more), they are:

  cycle-check
  dev-ino
  dup3
  dup3-tests
  fcntl-safer
  fcntl-safer-tests
  filevercmp
  filevercmp-tests
  fts
  getaddrinfo
  getaddrinfo-tests
  hostent
  i-ring
  i-ring-tests
  inet_ntop
  inet_ntop-tests
  isatty
  isatty-tests
  openat-safer
  openat-safer-tests
  opendirat
  ptsname_r
  ptsname_r-tests
  servent
  ttyname_r
  ttyname_r-tests

Some of the removed modules are still used pulled indirectly as
dependency of other modules.  There should be no behaviour change on
recent Linux distros, although older distros were not tested (adding
a module back is easy, anyway).

Remove accordingly unused automake variables, and ignored files.
