Commit f23efcbcc523 ("crypto: ctr - no longer needs CRYPTO_SEQIV") made
CRYPTO_CTR stop selecting CRYPTO_SEQIV.  This breaks IPsec for most
users since GCM and several other encryption algorithms require "seqiv"
-- and RFC 8221 lists AES-GCM as "MUST" be implemented.

Just make XFRM_ESP select CRYPTO_SEQIV.
