temp_metrics: add "--" when invoking ectool tmp006calrelease-R38-6158.B

ectool has switched over to using getopt for command line options parsing.
This breaks temp_metrics' invocation of "ectool tmp006cal" command since
some of the coefficients are negative and therefore start with "-".
getopt treats that as another command line option causing ectool to
barf.

BUG=chromium:422160
TEST=On a Pixel issue "sudo start temp_metrics" and check
/var/log/messages to ensure that no new messages such as "init:
temp_metrics main process ended, respawning" show up.
BRANCH=none
