kselftest/arm64: Specify SVE data when testing VL set in sve-ptrace

Browse source

[ Upstream commit 9e8ebfe677 ]

Since f916dd32a9 ("arm64/fpsimd: ptrace: Mandate SVE payload for
streaming-mode state") we reject attempts to write to the streaming mode
regset even if there is no register data supplied, causing the tests for
setting vector lengths and setting SVE_VL_INHERIT in sve-ptrace to
spuriously fail. Set the flag to avoid the issue, we still support not
supplying register data.
