remove-minimal.xml: Partial changes needed for FBE decryption

* This is only a partial commit. Some repos still need to be
  included manually, see the comment about android_frameworks_base.
  And some additional libs/dirs are needed from AOSP r34 source
  since they are not yet available (or updated) in the current omni
  repo at the time of this writing.

* Using AOSP android-8.0.0_r34 tag:

  For at least a build:
    Add: frameworks/base/core/java/android/content
    Add: frameworks/base/core/java/android/security

  For weaver:
    Add: hardware/interfaces/weaver

  For libkeymaster1.so -> libkeymaster_portable.so and libkeymaster_staging.so
    Replace: system/keymaster
    Replace: system/security/keystore

  For libkeyutils.so
    Add: system/core/libkeyutils
