Avoid sleep loop in rild.conf

[Loïc Minier]

Hi,

while reviewing other jobs, James Hunt kindly pointed out:
"""
Looking at these jobs, I noticed /etc/init/rild.conf - why aren't we using the upstart-local-bridge to avoid that horrid poll? Is it because rild.conf needs multiple getprop values? If so, you should be able to say in /etc/init/rild.conf

start on android-container init.svc.ril-daemon=running

script
  # query rild variables using getprop
end script
"""

it would be good to remove the ugly sleep loop indeed.

Cheers,
