sys/sys: Fix __builtin_is_aligned fallback
When the compiler doesn't provide __builtin_is_aligned we use
macro as a fallback. The macro was missing brackets around one
argument. This could lead to incorrect results when the argument is
more complex than a single stagement.
Fix this by adding the needed brackets.
