core: Allow to configure execute_directories execution behavior

This adds a new bitfield to `execute_directories()` which allows to
configure whether to ignore non-zero exit statuses of binaries run and
whether to allow parallel execution of commands.
In case errors are not ignored, the exit status of the failed script
will now be returned for error reposrting purposes or other further
future use.
