Subject: [PATCH] kselftest/arm64: Allow sve-ptrace to run on SME only
 systems

Currently the sve-ptrace test program only runs if the system supports
SVE but since SME includes streaming SVE the tests it offers are valid
even on a system that only supports SME. Since the tests already have
individual hwcap checks just remove the top level test and rely on those.
