[core] show correct crypt support result (fixes #2690)

If the crypt function is available as part of the standard
system library, then HAVE_LIBCRYPT will not be set, but
HAVE_CRYPT or HAVE_CRYPT_R will.

Make server.c test HAVE_CRYPT, HAVE_CRYPT_R  and HAVE_LIBCRYPT
to determine the correct value of crypt support.
