compat/fnmatch: fix off-by-one character class's length check

Character class "xdigit" is the only one that hits 6 character limit
defined by CHAR_CLASS_MAX_LENGTH. All other character classes are 5
character long and therefore never caught by this.

This should make xdigit tests in t3070 pass on Windows.
