encoding: avoid quadratic time complexity when json-encoding non-UTF8 strings

Apparently the code uses "+=" with a bytes object, which is linear-time, so the
whole encoding is quadratic-time. This patch makes us use a bytearray object,
instead, which has a(n amortized-)constant-time append operation.

The encoding is still not particularly fast, but at least a 10MB file
takes tens of seconds, not many hours to encode.

Note for future hackers of patchbomb: this file is a bit heavy on
wildcards in test expectations due to how many things like hostnames
tend to make it into outputs. As a result, you may need to perform the
following regular expression substitutions:
Mercurial-patchbomb/.* -> Mercurial-patchbomb/* (glob)
/mixed; boundary="===+[0-9]+==" -> /mixed; boundary="===*== (glob)"
--===+[0-9]+=+--$ -> --===*=-- (glob)
--===+[0-9]+=+$ -> --===*= (glob)
