u8800: Increase tmpfs size to fix adb sideload

Increase tmpfs size from the default 193MB which is 50% of the physical RAM
to 220MB which is enough to install cm11 (at least for now)
u8800: Disable unsupported BT features.
u8800: Remove chmod on ip.

/system is read-only. This is not possible.
u8800: Set RIL prop at build time rather than at boot time.
u8800: Remove unused mkdir/chmod ops.

Some of these have moved to init.rc, while others are not needed at all.
u8800: Update package names.

Make sure the packages we needget included. Remove unused packages.
libcamera: Remove dead code. Indent.
