kern/58149: aarch64: Cannot return from a signal handler if SP was misaligned when the signal arrived

Apply the kernel diff from the PR

1. sendsig_siginfo() previously assumed that user SP was always aligned to
  16 bytes and could call signal handlers with SP misaligned. This is a
  wrong assumption because aarch64 demands that SP is aligned *only while*
  it's being used to access memory. Now it properly aligns it before
  pusing anything on the stack.

2. cpu_mcontext_validate() used to check if _REG_SP was aligned and
  considered the ucontext invalid otherwise. This meant if a signal was
  sent to a process whose SP was misaligned, the signal handler would fail
  to return because the ucontext passed from the kernel was an invalid
  one. Now setcontext(2) doesn't complain about misaligned SP.
