Note that you are asking for the etymology of a Cebuano word, that would render this question off-topic in this site, so I can only hint a possible origin. The expression por vida was already used in the 16th century in the Spanish language. It was as a way of speaking used to persuade or force the concession of what is intended.
Example:
Por vida tuya que hagas esto.
It was also used as an assertion and as an oath (swear something on someone's life):
Daban los Jones tanto crédito, y autoridad à la berza, que juraban por vida de ella, como si fuera algun Dios.
You could also use por vida mía to swear on your own's life or express your determination to do something or make someone do something:
Por vida mia, que te disculpes agora.
This last sentence, written in 1642, can easily be translated as something like you'd better apologise now, goddammit, making the expression por vida mía a way of expressing anger, much like the Cebuano word porbida, which is used "to express anger, irritation, disappointment, annoyance, contempt, etc.". According to the Wikipedia, the language was heavily influenced by the Spanish language during the period of colonialism from 1565 to 1898. So it is quite plausible that the Cebuano expression porbida comes from the Spanish language given the similarities.
