latexmk: update to 459.

From v. 4.56 to 4.57
  Correct problem that in calculation of md5 checksum, an error
    sometimes occurs about malformed utf8 characters.  This can happen
    if the environment variable PERL_UNICODE is set.
  Add configuration variable $bibtex_fudge to allow to choose
    whether to use the fudge that made bibtex run correctly when
    an output directory (or aux directory) is specified.  (A
    planned future version of bibtex in TeXLive will not need
    the fudge.)

From v. 4.57 to 4.59
  Deal with double quote ('"') characters in files on command line to
    correspond to behavior of tex programs.  Remove balanced pairs,
    and give fatal error for unbalanced double quotes. (Note MiKTeX's
    tex programs simply remove unbalanced quotes.)  In all cases, the
    '"' character is not allowed in a filename read by tex and
    friends.
  Give fatal error when name of tex file on command line is either not
    allowed by tex and friends are gives problematic behavior.
  Use TEXINPUTS as search path for source files for custom
    dependency.
  Only give warning about differing expected and output filenames when
    the extensions differ.  All other cases gave only false positives.
  Do better to ensure xelatex gets its -no-pdf option.
