arm64/signal: Always allocate SVE signal frames on SME only systems

commit f26cd7372160da2eba31061d7943348ab9f2c01d upstream.

Currently we only allocate space for SVE signal frames on systems that
support SVE, meaning that SME only systems do not allocate a signal frame
for streaming mode SVE state. Change the check so space is allocated if
either feature is supported.
