Supported Android versions are changing in Firefox 46

A quick follow-up on this:

We noticed that Android API 14 (4.0.0–4.0.2) use is astonishingly low on
ARM, too, so we took this opportunity to kill support for that alongside
x86. See Bug 1237342 <>.

That means that both our ARM and x86 mainline builds are now *API 15+*

For the moment we continue to support our Gingerbread API 9-10 build, but
do follow Bug 1220184
<> for
EOL on that front.
