maint: use EXIT_SUCCESS and EXIT_FAILURE, not 0 and 1 to exit

Convert all uses automatically, via these two commands:
git grep -l '\<exit *(1)'|xargs --no-run-if-empty \
  perl -pi -e 's/\b(exit ?)\(1\)/$1(EXIT_FAILURE)/'
git grep -l '\<exit *(0)'|xargs --no-run-if-empty \
  perl -pi -e 's/\b(exit ?)\(0\)/$1(EXIT_SUCCESS)/'
* libparted/fs/fat/table.c (fat_table_get): Use symbolic exit codes.
* libparted/labels/vtoc.c (vtoc_update_format5_label_add): Likewise.
(vtoc_update_format5_label_del): Likewise.
(vtoc_update_format7_label_add): Likewise.
(vtoc_update_format7_label_del): Likewise.
* m4/parted.m4 (PARTED_CHECK_LIBPARTED): Likewise.
* parted/parted.c (do_quit): Likewise.
* parted/strlist.c (gettext_to_wchar, wchar_to_str): Likewise.
* parted/ui.c (reset_env, help_msg, non_interactive_mode): Likewise.
