set ASTVARRUNDIR=$(localstatedir)/run/asterisk as default path

When running asterisk as non-root and without this patch the pidfile wants
to go into /var/run/asterisk.pid. This directory is not writable for
the non-root user and changing permissions is not an option.
Putting it in /var/run/asterisk/asterisk.pid makes it possible
to set permissions on the /var/run/asterisk dir so everything
works as it should be.

Patched committed is based on pabelanger's patch.
