linux-generic: fix alignment of struct stat/statfs for nios2
The hard alignment of 8 was appropriate for most platforms for which 8-byte values are 8-byte aligned, but this is not true for the nios2 platform, so only align to the alignment of the 8-byte type on the platform. Remove the explicit alignment of struct statfs as it's redundant.
