posix: timer: Fix timer_obj alignment



This makes sure the heap posix_timer_slab provides objects aligned
compatible with the type timer_obj. It was previously set to align at 4
bytes. One example where this failed was on the SPARC which requires
access to int64_t to be 8-byte aligned.

In particular, struct timer_obj contains fields of type k_timer_t and
struct _timeout.

With this commit we now get the information on required alignment for
struct timer_obj from the compiler by using __alignof__().
