raid6check: Fix build of raid6check

After recent git pull 'make raid6check' did not work anymore, as
sysfs_read() was called with a wrong argument and as check_env()
was used by use_udev(), but not defined.

Replace sysfs_read(..., -1, ...) by sysfs_read(..., NULL, ...)

Move check_env() from util.c to lib.c
