Make sure the unwind section will be 32-bit aligned.

Explicitely mark the .data..lock_aligned explicitely 16-byte aligned
in vmlinux.lds.S although the previous ALIGN(16) statement already
does it right.

Add __aligned(16) to __lock_aligned define to ensure that such
variables will have an alignment of 16 in the sections of the object
files.
