[Fabrice Fontaine]

Fix the following build failure with gcc 4.8 raised since bump to
version 1.0.0 in commit ib832f6eb9d86920907c50901a99f13b44dd94647 and
https://github.com/google/fscryptctl/commit/9dba7224cbde07df25ba01146a2f6fb897bb9e56:

fscryptctl.c: In function 'string_to_mode':
fscryptctl.c:214:3: error: 'for' loop initial declarations are only allowed in C99 mode
   for (size_t i = 0; i < ARRAY_SIZE(mode_strings); i++) {
   ^
