Subject: cmd/swarm, swarm/api/http, swarm/bmt, swarm/fuse,
 swarm/network/stream, swarm/storage, swarm/storage/encryption,
 swarm/testutil: use pseudo-random instead of crypto-random for test files
 content generation (#18083)

- Replace "crypto/rand" to "math/rand" for files content generation
- Remove swarm/network_test.go.Shuffle and swarm/btm/btm_test.go.Shuffle - because go1.9 support dropped (see https://github.com/ethereum/go-ethereum/pull/17807 and comments to swarm/network_test.go.Shuffle)
