MINOR: startup: allow hap_register_feature() to enable a feature in the list

Browse Source 
This patch allows hap_register_feature() to enable a feature in the list
which was already registered and marked disabled.

This way we could enable automatically some features under certain
condition without the need of the USE argument with make and correctly
report its activation.
