Log Message:
Pull up following revision(s) (requested by rin in ticket #1220):

        sys/arch/amd64/include/param.h: revision 1.30

Bump STACK_ALIGNBYTES to (16 - 1) to satisfy requirement by AMD64
System V ABI in kernel level. This is because

(1) for LLDB, we want to bypass libc/csu (and therefore manual stack
     alignment in _start), and
(2) rtld in glibc >= 2.23 for Linux/x86_64 requires it.

Fix SEGV for Linux/x86_64 binaries with glibc >= 2.23, reported as

PR port-amd64/54052.
