raid6/test/test.c: bug fix: Specify aligned(alignment) attributes to the char arrays
Specifying the aligned attributes to the char data[NDISKS][PAGE_SIZE],
char recovi[PAGE_SIZE] and char recovi[PAGE_SIZE] arrays, so that all
malloc memory is page boundary aligned.
Without these alignment attributes, the test causes a segfault in
userspace when the NDISKS are changed to 4 from 16.
The RAID stripes will be page aligned anyway, so we want to test what
the kernel actually will execute.
