This reverts commit 1745f3a759.
Reason for revert:
1. The BUILD_VERSIONS.S is 1000, and thus it will prevent
the code from requiring new algorithms on devices whose
first sdk is 31 (e.g. cuttlefish), though these devices
should be treated as first launched with SDK S.
2. It will break #testValidationForAlgosAddedInS, because
the test code is using BUILD_VERSIONS.R to gate the test,
which is inconsistent with the implementation.
Bug: 181887451
Test: atest IpSecAlgorithmTest
