armv7hl-lge-hammerhead: Add all packages
armv7hl-lge-hammerhead: Add usb-moded packages and comment kernel

SailfishOS doesn't install the kernel, guess because hybris-boot has got
it.

Also install usb-moded packages although I'm not sure we need all of
them.
armv7hl-lge-hammerhead: Don't pack KS

We don't need it.
maui-mobile.yaml: Set password to maui

Otherwise it becomes harder to connect to a headless device.
maui-mobile: Add connman-test

Comes in handy should we need cli tools.
armv7hl-lge-hammerhead: Add minimer
armv7hl-lge-hammerhead: Unmask sshd-keys

Otherwise I doubt will ever see ssh running on the device.
