kselftest/arm64: Corrupt P0 in the irritator when testing SSVE

Browse Source 
When building for streaming SVE the irritator for SVE skips updates of both
P0 and FFR. While FFR is skipped since it might not be present there is no
reason to skip corrupting P0 so switch to an instruction valid in streaming
mode and move the ifdef.
