install-build-deps-android.sh complains about missing ant-1.8

install-build-deps-android.sh complains about missing ant-1.8 on Ubuntu
13.04. The package is simply called "ant" since Ubuntu 12.04. The script
is checking for Ubuntu 12.x but fails to identify 13.x. This patch fixes
the script so that "ant" package is installed on Ubuntu >= 12.x, instead
of "ant-1.8".
