fp5280g2: Fix missing power-supply-monitor configs

Since the SYSTEMD_ENVIRONMENT_FILE_${PN} defined in
obmc-phosphor-systemd.bbclass, and the phosphor-power_%.bbappend have
not inherit obmc-phosphor-systemd, so all of the
power-supply-monitor-*.conf are not installed.

Tested: Built fp5280g2 successfully and includes the
power-supply-monitor configs.
