arm64: ptrace: Use ARM64_SME to guard the SME register enumerations

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2122232

    We currently guard REGSET_{SSVE, ZA} using ARM64_SVE for no good reason.
    Both enumerations would be pointless without ARM64_SME and create two empty
    entries in aarch64_regsets[] which would then become part of a process's
    native regset view (they should be ignored though).

    Switch to use ARM64_SME instead.

    Fixes: e12310a ("arm64/sme: Implement ptrace support for streaming mode SVE registers")
