package/systemd-bootchart: add BR2_PACKAGE_SYSTEMD_BOOTCHART_ARCH_SUPPORTS

Since commit f93596d8ba82354efb545fe91449627e6c896ce1, systemd is
enabled on arc however systemd-bootchart is not available on this
architecture so add a BR2_PACKAGE_SYSTEMD_BOOTCHART_ARCH_SUPPORTS from
the information retrieved in src/architecture.h
