Fix: utils: pass env to child process explicitly (bsc#1205925)

A bug in python stardard library, python/cpython#100516, make
environment variables, `COLUMNS` and `ROWS` to be added at fork. These
environment variables may make some of the commands called by crmsh to
truncate its output even if those commands are not writing to the
terminal.

Passing argument `env` explicitly is a workaround for the python bug.
