[meta-oe][PATCHv2] snort: add openssl PACKAGECONFIG

[Martin Jansa <martin.jansa@gmail.com>]

* otherwise the result isn't deterministic
  WARN: packages/armv5te-oe-linux-gnueabi/snort/snort/latest lost dependency on  libcrypto

* enable it by default, disabling currently doesn't work, because there are --with flags for
  openssl, but then configure.in still checks for sha.h header with
  AC_CHECK_HEADERS([openssl/sha.h],, SHA_H="no")
  and autodetects it, I'll leave patching configure to someone who
  is actually using snort (this issue was reported many times and
  nobody seems to care).
