fix(susfs-revert-patches): fix fdinfo.c revert perl command escaping

The revert used s/// delimiters with \/ to escape forward slashes
in the comment block (/* */). But \\ in the replacement produces a
literal backslash, making the following / the end of the replacement.
Switch to s{}{} delimiters so /* and */ need no escaping at all.
