dependencies.tsv: Update juju/utils on 2.0

[bz2]

Fixes lp:1468752 on 2.0 branch by bringing in new code
from utils to handle carriage returns when using gocrypto
ssh on windows clients.

Note this also brings in some other bug fixes from utils
changes that have not yet been brought to the 2.0 branch.

QA steps

• Build and bootstrap on windows
• juju switch controller
• juju ssh 0
• Run commands on the remote machine, ensure they work

[bz2]

From the check script, there are build issues from minor api changes in the interveening utils commits. Investigating how invasive just adapting the code here as well is.

Can't really review this until the breakages are fixed. We'll need to do that sooner or later, so might as well be in here.

!!build!!

I don't have windows to check QA.

Also, I'd rather see the cherry picked commit and the update(s) to dependencies.tsv in separate commits -- even if in the same PR.

LGTM other than that nit.
