[U-Boot] [PATCH v3 13/18] buildman: Provide an internal option to clean the outpur dir

[Simon Glass]

For testing it is useful to clean the output directory before running a
test. This avoids a test interfering with the results of a subsequent
test by leaving data around.

Add this feature as an optional parameter to the control logic.
