[moblab] fix wmatrix not updating due to bad imports

wmatrix update scripts try to import whining, but that
package does not exist, and is not used anywhere in
any of the update scripts that imported it. Removing
it and wmatrix updater runs without errors, tests
show up shortly after completion as expected.

BUG=chromium:833521
TEST=Build and test on local device that recently run
tests appear on wmatrix.
