Fix residual self.detected usage in packages and dumpsys_receivers

These modules still used self.detected.append() which no longer exists
after the alertstore migration. Converted to alertstore calls:
- packages.py: ROOT_PACKAGES detection → alertstore.high()
- dumpsys_receivers.py: receiver IOC match → alertstore.critical()
