linux-user: Remove unnecessary 'aligned' attribute from TaskState
The linux-user struct TaskState has an 'aligned(16)' attribute. When
the struct was first added in commit 851e67a1b46f in 2003, there was
a justification in a comment (still present in the source today):
/* NOTE: we force a big alignment so that the stack stored after is
aligned too */
because the final field in the struct was "uint8_t stack[0];"
But that field was removed in commit 48e15fc2d in 2010 which
switched us to allocating the stack and the TaskState separately.
Because we allocate the structure with g_new0() rather than as
a local variable, the attribute made no difference to the alignment
of the structure anyway.
Remove the unnecessary attribute, and the corresponding comment.
