common: cli_hush: Restore clear local variable support

The u-boot hush shell doesn’t support the unset command to clear a
variable and therefore an empty value ("c=") should be a valid value
for the set_local_var function to clear the variable. This partial
reverts commit aa722529635c ("common: cli_hush: avoid dead code") and
only checks for a `=` in the string. Additionally explicit call the
unset_local_var function to remove the variable if the value is empty.
