@anthy: bugfixes from Fedora

Bump PKGREVISION.

From Showta Ishizaki in PR 60727.

Do not dereference a NULL xstr.  reorder_by_suffix passes anthy_xstrcmp the
result of anthy_get_nth_xstr(0), which is NULL whenever the first value of
the matching SUFFIX_HISTORY row is not a string, and anthy then dies with
SIGSEGV inside anthy_set_string -- so every conversion of a word ending in a
suffix takes down whatever loaded the library.  anthy's own record writer can
produce such a row: write_quote_xstr puts nothing between the quotes when the
value it is handed is empty or damaged.

Fedora added this guard in 2013 as anthy-fix-segfault.patch, for ibus-anthy
crashing in anthy_xstrcmp (their bug 973127), and anthy-unicode -- the fork
that is still maintained -- has the same guard in src-diclib/xstr.c.
