[toolchain-utils] Update waterfall report (email, archive, pruning).

The CL udpates the waterfall summary report script to: 1). Send an
email containing the reports to whoever ran the script; 2). Copy the
generated reports to
/google/data/rw/users/mo/mobiletc-prebuild/waterfall-reports
so everyone on the team can see all the reports;  3). Prunes failures
that are older than 7 days from the failure dictionary.

BUG=None
TEST=Tested in my own directory.
