LU-2877 Add a roundtrip delay in sanity test 34h

It seems we are still getting false failures in test 34h due to
overloaded server that takes longer than 2 seconds to process
a request.
To even things out - do another sync RPC to OST first before
starting the timeout.

LU-1199 lbuild: Fix error handling

Improper grouping of expressions in the error() function meant
that even a simple "lbuild -h" would trigger a backtrace, and email to
someone at whamcloud.com.  That is fixed here.

Also stop sending email to a static email address on errors.

Also fix a minor typo.
