Bug 1220887 - Make 'base' Gradle project in the srcdir. r=sebastian

This is the last Gradle project that isn't in the srcdir.  Since base/
doesn't have the correct package prefix directory structure, we still
need to symlink, but we only need one link.  This effectively
deprecates |mach gradle-install|.

This should improve the robustness of our Gradle configuration,
ensuring that we always have projects to import.  Since
settings.gradle executes very early in the IDE import project
sequence: before Gradle project evaluation time, and thus before any
Gradle task is executed, we should always see a complete project.  (It
was possible to see incomplete Gradle configurations if |mach
gradle-install| hadn't been run at just the right time.)
