Nick Alexander 1764740990 Bug 1543982 - Part 2: Don't invoke mach build ... recursively. r=emilio
This commit avoids moz.build tasks when we're already within `mach
build`.

This is belt-and-braces: from within `mach build`, we want the main
moz.build dependency graph to arrange for the Gradle invocations to be
in the right state.  It's only in other situations, like `mach android
...` or invocation from Android Studio, that we want Gradle to arrange
to be in the right state vis. moz.build.
