Clean package manager caches on boot #323

On some devices, the system time is set too late in the boot process. This, for some reason, causes the package manager service to not update the cache entry in /data/system/package_cache despite the mtime of the apk being newer than the mtime of the cache entry [1]. The outdated cache entry causes BCR to crash with an error about the app theme not being derived from Theme.AppCompat. This commit works around the issue in a brute force way by deleting BCR's package manager cache entry on every boot.

Fixes: #275, #303, #307

Some devices don't set the system time properly during boot, causing
Android's package manager to fail to invalidate cached package info.
Work around this by forcibly deleting the relevant cache files.
