Turn off carrier provisioning by default

Whether or not to use carrier provisioning is a setting hidden to the
end user that is currently not set. Unfortunately, on some carriers that
may result in it being set to yes, or effectively set to yes, without
other accompanying changes that must occur, such as setting a tethering
apn and possibly having a carrier provisioning app, resulting in hitting
a paywall when a tethering plan exists, or, worse having nothing happen
at all when you try to tether since the data doesn't have an apn set.

*Current button actions for home can be set via fw/base overlay.
 This is very useful for devices such as m7 that have no menu key
 since actions like double-tap home > menu can be set. Once RC is
 implemented, the ability to change actions on the fly can be introduced.
