Dockerfile missing librsvg2-bin dependency

[srwareham]

I tried running the following

git clone --recurse-submodules https://github.com/coredevices/pebbleos
cd pebbleos
python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
./waf configure --board obelix_pvt
./waf build

And at the last step got the following error

[ 615/1997] Compiling resources/normal/base/images/Pebble_50x50_Car_rental.svg
Waf: Leaving directory `/hostmount/pebbleos/build'

Installing librsvg2-bin resolved the issue.
