[OE-core] [PATCH] resulttool/resultutils: Fix unicode error handling

[Richard Purdie]

This error handling didn't work as expected since upon failure it would
inject bytestreams back into the code leading to tracebacks.

Instead, ignore the decode errors. Fixes:

Traceback (most recent call last):
  File "/home/pokybuild/yocto-worker/a-full/build/scripts/resulttool", line 78, in <module>
    sys.exit(main())
  File "/home/pokybuild/yocto-worker/a-full/build/scripts/resulttool", line 72, in main
    ret = args.func(args, logger)
  File "/home/pokybuild/yocto-worker/a-full/build/scripts/lib/resulttool/store.py", line 70, in store
    resultutils.save_resultsdata(results, tempdir, ptestlogs=True)
  File "/home/pokybuild/yocto-worker/a-full/build/scripts/lib/resulttool/resultutils.py", line 178, in save_resultsdata
    f.write(sectionlog)
TypeError: write() argument must be str, not bytes
