Update WebView's android framework jar to 5.1.0_r1.

Update WebView's android framework jar to 5.1.0_r1.

Now that Android 5.1 is released, use the Android 5.1.0_r1 release tag
from AOSP to build an up-to-date framework jar instead of a snapshot of
AOSP master. This removes the need for a manifest recording the exact
build used as it's a real tagged release.

The new jar was already landed separately in
crrev.com/81b497cdc14855e407e4406dac8a47346fa7ce8e as Rietveld doesn't
handle large binaries well.

Added a small gypfile tidyup while I'm here - making the APK name come first in
the APK definition, and moving shared_resources: 1 to the common gypi file since
it's mandatory to make a working apk and everything using the gypi set it
already.

LGTM, thanks

cc'ing sgurun. we can't land this until the downstream CL to switch away from
the old jar has landed, since this removes that jar.
