Bug 1362164 - Remove mozharness code to print ccache stats; r=ted

I was going to inline "enable_ccache" into buildbase.py because AFAICT
its value is effectively "if not windows." However, I realized that
all this is doing is dumping ccache stats (something the build system
itself is in a better position to do because it actually knows if
ccache is enabled). Then I realized we don't use ccache directly
any more in automation because we use sccache (or at least that's the
way it should be).

Since there's no need for this ccache code in mozharness, this commit
deletes it. If we want it back, we can add the functionality to
`mach build`.
