Various small cache cleanups.

Add the machine used for running the test to benchmark run; use the
actual data from that machine for generating the cache entry for the
run.  Also make sure, when calculating the common checksums for looking
machines up in the cache, that all the machines being used actually have
the same checksum.  Also add a cache_keys.txt file to the cache directory,
to allow people to see what was used for generating the cache
entry/checksums.

BUG=None
TEST=Tested in my directory.
