meson: portname was set too early

portname is set to host_system, but host_system might still be changed
later in the file.  As a consequence, platforms where host_system is
changed later wouldn't find some of their platform-specific files
(driven by portname), and the build would fail.  Move the assignment
of portname further down after the last change of host_system (but
before further overriding assignments to portname).
