[U-Boot] [PATCH v3 12/18] buildman: Correct counting of build failures on retry

[Simon Glass]

When a build is to be performed, buildman checks to see if it has already
been done. In most cases it will not bother trying again. However, it was
not reading the return code from the 'done' file, so if the result was a
failure, it would not be counted. This depresses the 'failure' count stats
that buildman prints in this case.

Fix this bug by always reading the return code.
