build: update gnulib and improve --with-openssl configure help

* configure.ac: Use gl_SET_CRYPTO_CHECK_DEFAULT() to set the
coreutils default for --with-openssl early, so that the
help text can be provided in a standard and complete form.
* gnulib: Update to incorporate a build fix on platforms
with only some of md5 and sha* implemented by libcrypto.
