[PATCH 1/3] yocto-check-layer: Add --run-tests to select the tests to run

[Otavio Salvador <otavio@ossystems.com.br>]

The common and distro tests ignore --machines, so a BSP layer checked in
several runs, one per group of machines, repeats them in each. Add
--run-tests, taking <module>[.<class>[.<name>]] as oe-test does, so the
common tests can run once and only the BSP ones in the others. A name
matching no test is an error rather than a run that checked nothing.

Tested on meta-freescale with "--run-tests common distro" and
"--run-tests bsp --machines imx8mm-ddr4-evk imx8mn-ddr4-evk".
