Accessing and setting shadow_progname is not as straight-forward as it might seem due to the way of linking libshadow_la with libsubid and programs. Enforce the usage of log_get_progname to make this less messy. With last entry of shadowlog_internal.h gone, remove the file entirely. Signed-off-by: Tobias Stoeckmann <tobias@stoeckmann.org>
