core/execute: report invalid environment variables from files
Because "export key=val" is not supported by systemd, an error is logged
where the invalid assignment is coming from.
Introduce strv_env_clean_log() to log invalid environment assignments,
where logging is possible and allowed.
parse_env_file_internal() is modified to allow WHITESPACE in keys, to
report the issues later on.
