freebsd guile port

[Alexey Antipov]

Hi!
During compilation of the lang/guile port used HAVE_CRYPT_H macros, whis is
undefined on freebsd. The "crypt" function in posix.c depends on it, and
does not compiled in.

try
>(crypt "foo" "bar")
and you will get "Unbound variable: crypt" message

As we  definitely have crypt(3) in libcrypt, the HAVE_CRYPT_H macros is
unneeded.

sample patch which corrects the problem:
