Michael Anselmi 95f698eb46 nss: support logging TLS secrets
As described at
[NSS Key Log Format](https://developer.mozilla.org/en-US/docs/Mozilla/Projects/NSS/Key_Log_Format),
starting with NSS 3.24, optimized builds using the Makefile must set
the make variable `NSS_ALLOW_SSLKEYLOGFILE=1` to support logging TLS
secrets.

Please note that with this change, users must still set the
`SSLKEYLOGFILE` environment variable at runtime to enable logging of TLS
secrets.

## Example

### Before change

```
% env CURL_SSL_BACKEND=nss SSLKEYLOGFILE="${HOME}/tls-secrets.log" curl -s https://www.google.com > /dev/null

% cat "${HOME}/tls-secrets.log"
cat: /Users/manselmi/tls-secrets.log: No such file or directory
```

### After change

```
% env CURL_SSL_BACKEND=nss SSLKEYLOGFILE="${HOME}/tls-secrets.log" curl -s https://www.google.com > /dev/null

% cat "${HOME}/tls-secrets.log"
# SSL/TLS secrets log file, generated by NSS
CLIENT_RANDOM a0388fe83d79a1e70f18fc86398e5081e6dda7bc35f740244b5f62d150a7ec6f 4b53a5750c892d74ef16ced6e356abb8b9b1885763a38c65cddf169e395ab89a2ac1e2ab5c0c1f8af5217a4d90acb94e
```

Closes #40454.

Firefox can pick this up instead of the built-in library, resulting in
random crashes without meaningful explanation.
