[PATCH] src/splice-test.c: use memalign instead of aligned_alloc

[David Sterba <dsterba@suse.com>]

The build fails on SLE11 as the function aligned_alloc is not available
there. Replace it by memalign that has the same semantics and is
commonly used in fstests code base. aligned_alloc has additional
requirements on the alignment and buffer size but that is ok as the
buffer is defined in multiples of the alignment.
