scripts: runners: esp32: remove print() call

This print() call was introduced as part of commit 16571db029 ("soc:
esp32: add support to mcuboot build") probably as a leftover from
debugging stage. Remove that, so flash command is not printed by
default. Those commmands can be easily printed by passing -v flag to
`west -v flash ...` command.
