libsodium: add emscripten support to the libsodium recipe

[laci-aura]

libsodium/1.0.19

The --disable-ssp option was missing which lead to linking errors due to the missing stack check functions in emscripten.

Also, the libsodium-provided

./dist-build/emscripten.sh --standard

script results in running:

./configure --enable-minimal --disable-shared "--prefix=libsodium-stable/libsodium-js" --without-pthreads --disable-ssp --disable-asm --disable-pie

so I've added the missing minimal/pthreads/asm/ssp options to the recipe to mimic the standard emscripten build options

• I've read the contributing guidelines.
• I've used a recent Conan client version close to the currently deployed.
• I've tried at least one configuration locally with the conan-center hook activated.

^{Note: To save resources, CI tries to finish as soon as an error is found. For this reason you might find that not all the references have been launched or not all the configurations for a given reference. Also, take into account that we cannot guarantee the order of execution as it depends on CI workload and workers availability.}
