gnu: openssl: Remove run-time dependency on Perl.

This shrinks the closure of OpenSSL from 154 MiB to 73 MiB.

* gnu/packages/patches/openssl-c-rehash.patch: New file.
* gnu-system.am (dist_patch_DATA): Add it.
* gnu/packages/tls.scm (openssl)[source]: Use it.
  [arguments]: Add 'remove-miscellany' phase.
* gnu/packages/certs.scm (nss-certs)[native-inputs]: Add PERL.
