Install mingw in Docker

[sjanusz-r7]

This PR installs mingw in Docker so that the module json file can be populated with windows encrypted shell entries.

Verification

From #15652

• docker build -t metasploitframework/metasploit-framework:latest .
• ./tools/automation/cache/update_module_cache.sh
• Verify the updated db/modules_metadata_base.json file includes encrypted payloads metadata
• Verify the encrypted payloads are searchable in msfconsole without mingw being installed on the host machine, and that they are usable - but provide the user a warning that mingw is missing

Looks like the 32 bit version isn't generated still, am I missing anything? 👀

[adfoster-r7]

Looks like sorting out the 32 bit cache information will be more effort, let's land this separately

Release Notes

This updates msfconsole's search functionality to include the 64 bit variant of payload_windows/x64/encrypted_shell payloads

[adfoster-r7]

Confirmed that Jenkins grabbed these in now too 0296e59
