Bug 1575804 - Don't decode the result from check_cmd_output. r=froydnj

Browse Source 
Bug 1575135 changed check_cmd_output to return unicode strings, but a
couple places were already trying to do their own decoding, which now
can fail. Remove those.

Interesting the decoding was previously broken on Windows, this
actually fixes it (the output of hg config is not actually utf-8 on
Windows).
