Simon Chopin bbd60a96ec fish: enable the legacy provider if build against OpenSSL3
OpenSSL 3.0 disables a number of "legacy" algorithms by default, and we
need to enable them manually using their provider system. Note that
explicitly loading a provider will disable the implicit default
provider, which is why we need to load it explicitly.

Closes #2629

Signed-off-by: Simon Chopin <simon.chopin@canonical.com>

V2:
  * use a local OSSL_LIB_CTX to avoid leaking the legacy algorithms
    into the main SSL context.
  * Simplify the fish_init() error paths by calling fish_deinit()
