fix: add no-module to openssl static build

Ever since the update to openssl 3.x we have been building static openssl
ever so slightly incorrect. Without the `no-module` configuration option
openssl still tries to provide some non-core modules (like the legacy provider)
as a shared library. However luvi has no way to bundle this, and so ever since
the update to openssl 3.x we have been unable to use any of the legacy ciphers
in luvi.

I used the following script to ensure the provided fix actually works for the
legacy provider:

```lua
local openssl = require 'openssl'

print(openssl.errors())

local ctx = openssl.cipher.get('blowfish') -- any cipher provided by legacy works here
print(ctx)

print(ctx:cipher('123', '456', '789'))
```

Before this fix:

```
C06BE223E67B0000:error:12800067:DSO support routines:dlfcn_load:could not load the shared library:crypto/dso/dso_dlfcn.c:118:filename(.../lib64/ossl-modules/legacy.so): .../lib64/ossl-modules/legacy.so: cannot open shared object file: No such file or directory

openssl.evp_cipher: 0x7be623dd52d8
nil     unsupported     50856204
```

After this fix:

```

openssl.evp_cipher: 0x7fca1a4d8a98

```

Alongside fixing the static build of openssl, this also fixes the intermittent
issue with lua-openssl triggering the incompatible pointer types error by
silencing the warning, which lua-openssl does internally but only for clang.
