test/params_conversion_test.c: fix the use of strtoumax and strtoimax on VMS
We do this by making them aliases for strtoull and strtoll, since long
long is the current largest integer that have this sort of routine on
VMS.
# define strcasecmp _stricmp
# endif
+# ifdef OPENSSL_SYS_VMS
+# define strtoumax strtoull
+# define strtoimax strtoll
+# endif
+
typedef struct {
OSSL_PARAM *param;
int32_t i32;
