hal: reject Manjaro packages with extreme prejudice

Adding a Manjaro blocklist that refuses to install any of:
pamac, manjaro-hello, manjaro-settings-manager,
linux-manjaro, mhwd

Trigger message:
  ⚠ Detecting Manjaro-associated package...
    🎵 please i just wanna die, die, die 🎵
    it's muffin time
    have you had a muffin today?
    → '{pkg}' is Manjaro garbage. We don't do that here.
    Installation aborted for your own safety.

Works in both wrapper mode (hal install <pkg>) and
native mode (hal --self install <pkg>).
