This is wrong. "use_nss" means "use_nss for everything, including cert
verification"

['use_openssl==1', {
  'sources': [
    'renderer/webcrypto_impl_openssl.cc',
  ],
  'dependencies': [
    '../third_party/openssl/openssl.gyp:openssl',
  ],
}, {
  'sources': [
    'renderer/webcrypto_impl_nss.cc',
  ],
  'conditions': [
    ['os_posix == 1 and OS != "mac" and OS != "ios" and OS != "android"', {
      'dependencies': [
        '../build/linux/system.gyp:ssl',
      ],
    }, {
      'dependencies': [
        '../third_party/nss/nss.gyp:nspr',
        '../third_party/nss/nss.gyp:nss',
      ],
    }],
  ],
}]

Don't forget that you will also need to update the dependencies, since you're
using NSS/OpenSSL functions.
