Restore kernel requirements for frozen matrices.

Requirements for legacy/1/2.xml has changed because
android-base.cfg files are changed. These files should
build from an older snapshot of the requirements.

Fixes: 78576469
Test: builds
Test: vts_treble_vintf_test

Change-Id: I908ebbe495ae06f983ef983a1be7937cf6be1c12
