fixing the /usr/bin/ld: cannot find -lGLESv2 error

[stephaneAG]

After an error while trying to compile npm install node-opengv-canvas & digging an answer from https://raspberrypi.stackexchange.com/questions/77619/where-is-legl-lglesv2, I guess this may solve the troubles ;p

Also, do you support dispmanX ? (.it 'd be really cool to have a transparent background canvas to be able to see stuff on layers below it ;p )

Thanks for opening & openvg-canva btw :)

Keep up the good work ++
