ZTS: Use ksh and current environment for user_run 

The current user_run often does not work as expected.  Commands are run
in a different shell, with a different environment, and all output is
discarded.

Simplify user_run to retain the current environment, eliminate eval,
and feed the command string into ksh.  Enhance the logging for
user_run so we can see out and err.
