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.
