The CONFIG_MASK in hostw.h includes CONFIG_START_DELAY, which
correlates to an option that is not actually used in host watchdog. As
a result, the recently added check that verifies all options in the
CONFIG_MASK are set fails, and the host watchdog fails to launch.
This update removes the unused CONFIG_START_DELAY bit from
CONFIG_MASK.
