kselftest/arm64: Don't require FA64 for streaming SVE+ZA tests

During early development a dependedncy was added on having FA64
available so we could use the full FPSIMD register set in the signal
handler which got copied over into the SSVE+ZA registers test case.
Subsequently the ABI was finialised so the handler is run with streaming
mode disabled meaning this is redundant but the dependency was never
removed, do so now.
