This simplifies the libmagic patch:
- in upstream the HAVE_STRERROR check has been removed
- in upstream library the HAVE_SIGNAL_H has been removed
- indentations syncs with the upstream library
- some irrelevant changes removed from the patch (log comment), upstream
has this correctly logged already so no need to patch the comment.
