Xiao Yang 84fdfc5d8a fstests: Fix buffer alignment of aiocp
In generic/252, aiocp with DIRECT will fail and return EINVAL on
4096 sector size block device, because the default 512 alignment
defined in aiocp is not aligned with 4096.

Please see the following error:
----------------------------------------------------------
read missing bytes expect 8388608 got -22
----------------------------------------------------------

We use '-a' option to specify a proper alignment size in all tests
that call aiocp with DIRECT.
