[U-Boot] [PATCH v2] buildman: Translate binutils output to UTF-8

[Daniel Schwierzeck <daniel.schwierzeck@gmail.com>]

binutils are using localized output. On systems with locales and special
characters this leads to exceptions like this:

Exception in thread Thread-7:
Traceback (most recent call last):
  File "/usr/lib/python2.7/threading.py", line 801, in __bootstrap_inner
    self.run()
  File "/u-boot/tools/buildman/builderthread.py", line 475, in run
    self.RunJob(job)
  File "/u-boot/tools/buildman/builderthread.py", line 456, in RunJob
    self._WriteResult(result, job.keep_outputs)
  File "/u-boot/tools/buildman/builderthread.py", line 333, in _WriteResult
    print >>fd, dump_result.stdout,
UnicodeEncodeError: 'ascii' codec can't encode characters in position 75-76: ordinal not in range(128)

Always encode the value of CommandResult::stdout to UTF-8 before
writing it to stdout or a log file.

Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>

Changes in v2:
- encode all occurences of CommandResult::stdout after spawning binutils to UTF-8
- reworded commit message
