This is an incremental change towards supporting shared libraries
for VxWorks on aarch64.
The aarch64-vx7r2 compiler supports compilation with -fpic/PIC. This
change adds aarch64 to the list of CPUs for which GNATLIB_SHARED maps to
gnatlib-shared-dual for vxworks7r2, so "make gnatlib-shared" actually
builds a shared lib.
While other adjustments will be needed to get the runtime tests to pass,
this one is a necessary step and doesn't impair the rest.

* Makefile.rtl: Add aarch64 to the list of CPUs for which
GNATLIB_SHARED maps to gnatlib-shared-dual for vxworks7r2.
# Turn on shared gnatlib for specific vx7r2 targets for RTP runtimes. Once
# all targets are ported the target_cpu selector can be removed.
