Maint: gnulib: refresh crypto/md5 module (after ~7 years, bit overdue)
Also avoid potentially arising dependency on OpenSSL -- people are free to require that using --with-openssl, but let's keep that out by default (as used to be the case before). Moreover, "nutritious" dependency on kernel-provided crypto (requires dozen of other Gnulib modoles) has explicitly been cut off as of preceding commit. Gnulib version used for the rebootstrap: a18f7ce3c.
