phosphor-power: Fix pkg_postinst script

The pkg_postinst script uses the variable OBMC_POWER_SUPPLY_INSTANCES
that is not availabe during the post installation. This results in the
links of power-supply-monitor@.service are not created.

Use `@d.getVar()` to get the variable from bitbake fixed the issue.

Also removes the default OBMC_POWER_SUPPLY_INSTANCES, let the build fail
when OBMC_POWER_SUPPLY_INSTANCES is not defined. Otherwise such issues
are only found at runtime.

Tested: Verify the witherspoon build contains the
        power-supply-monitor@.service links;
        Unset OBMC_POWER_SUPPLY_INSTANCES, verify the build fails due to
        installation failure.
