xstrtol: fix test failure on mingw

[Bruno Haible]

The tests test-xstrtol.sh, test-xstrtoimax.sh, test-xstrtoumax.sh, for two
reasons:
  1) The test wants to filter out the program name from the error message,
     but this does not work on mingw: when the error message is
       c:\work space\gltests\test-xstrtol.exe: invalid X argument
     it is no easy to determine where the file name end and where the error
     message begins. In particular, searching for the first colon does not work.
  2) The output has CRLFs, but is compared against expected output with only 
NLs.

This fixes it.

        Fix test failures on mingw.
        * tests/test-xstrtol.c (print_no_progname): New function.
        (main): Install it in error_print_progname hook.
        * tests/test-xstrtol.sh: Convert CR/LF to NL in output.
        * tests/test-xstrtoimax.sh: Likewise.
        * tests/test-xstrtoumax.sh: Likewise.
