mke2fs, tune2fs, resize2fs: Use floating point to calculate percentages
When calculating the number reserved blocks, use floating point for
better accuracy, since for big filesystems it really makes a
difference. In addition, mke2fs and tune2fs accepts a floating point
number from the user, so they should provide that level of accuracy.
