cmd/coordinator, internal: move benchmark building to separate package
This moves getSourceTgz* to a new package called sourcecache. The
original functions couldn't be left in coordinator.go because that
would cause a single process to have multiple caches.
The code for building and running benchmarks is moved into the buildgo
package, and the public API becomes GoBuilder.EnumerateBenchmarks and
Run on the resulting BenchmarkItem objects.
