crypt.h: remove initialized

* missing/crypt.h (struct crypt_data): remove unnecessary member
  "initialized".
* missing/crypt.c (des_setkey_r): nothing to be initialized in
  crypt_data.
* configure.in (struct crypt_data): check for "initialized" in
  struct crypt_data, which may be only in glibc, and isn't on AIX
  at least.
