Bug 1515004 - Move --with-android-sdk to moz.configure. r=nalexander Since ./mach bootstrap installs Android SDK into ~/.mozbuild, we should detect this location as default SDK install path. Also, --with-android-max-sdk and --with-android-min-sdk are still in android.m4 because confvars.sh sets MOZ_ANDROID_MIN_SDK_VERSION.
