package/php: security bump to version 7.4.11

- Fix CVE-2020-7069: In PHP versions 7.2.x below 7.2.34, 7.3.x below
  7.3.23 and 7.4.x below 7.4.11, when AES-CCM mode is used with
  openssl_encrypt() function with 12 bytes IV, only first 7 bytes of the
  IV is actually used. This can lead to both decreased security and
  incorrect encryption data.
- Fix CVE-2020-7070: In PHP versions 7.2.x below 7.2.34, 7.3.x below
  7.3.23 and 7.4.x below 7.4.11, when PHP is processing incoming HTTP
  cookie values, the cookie names are url-decoded. This may lead to
  cookies with prefixes like __Host confused with cookies that decode to
  such prefix, thus leading to an attacker being able to forge cookie
  which is supposed to be secure. See also CVE-2020-8184 for more
  information.
