[roll] Roll fuchsia [gpio][util] Add interrupt functionality

Add the ability to wait on a GPIO interrupt to gpioutil. The interrupt
command accepts a single argument specifying the interrupt mode, waits
for the interrupt to trigger once, then exits.

Test: gpioutil-test
Test: Ran gpioutil interrupt on vim3, then used gpioutil in a different
      shell to change the pin state and trigger the interrupt
