Escape parentheses in Makefile

"make install" crashes when --enable-install-cron has been used at
configuration stage:

if [ ( -z "/usr/lib/systemd/system" -o ! -d /usr/lib/systemd/system ) -a
! -d /etc/cron.d ]; then \
        if [ ! -d /etc/cron.hourly -o ! -d /etc/cron.daily ]; then \
                su root -c "crontab -l > /tmp/crontab-root.save"; \
                /bin/cp -a /tmp/crontab-root.save ./crontab-root.`date
'+%Y%m%d.%H%M%S'`.save; \
                echo "USER'S PREVIOUS CRONTAB SAVED IN CURRENT DIRECTORY
(USING .save SUFFIX)."; \
                su root -c "crontab cron/crontab"; \
        fi \
fi
/bin/sh: -c: line 0: syntax error near unexpected token `-z'
/bin/sh: -c: line 0: `if [ ( -z "/usr/lib/systemd/system" -o ! -d
/usr/lib/systemd/system ) -a ! -d /etc/cron.d ]; then \'
make: *** [install_all] Error 1

This is because parentheses need to be escaped in Makefile.in.
