package/snort: build with OpenAppID support if luajit/openssl is enabled

Since version 2.9.12, OpenAppID [1] is enabled by default.

OpenAppID depends on luajit and openssl. If we leave it enabled by
default, snort would require luajit. Since luajit is not available on
all architectures, that would limit the usage of the snort package.

Since not all users will need/use OpenAppID, let's leave it disabled by
default. To build with OpenAppID support, the user will need to enable
luajit and libssl.

Also, it is necessary to apply a patch to fix a compile error when
building OpenAppID with uclibc and musl. The build fails when
dereferencing the rpcent structure because rpc.h is not been included.
