samba4: bump to version 4.4.0

libaio support is now automatic so drop the enable/disable (it will fall
back to pthread aio if libaio is not present).

0002-build-improve-stack-protector-check.patch is upstream so remove it.

-Subject: [PATCH] build: improve stack protector check
-
-Testing a toolchain for proper -fstack-protector must go beyond ensuring
-the compiler and linker accept the option.
-If the test C program does nothing with the stack then guards aren't
-inserted and/or are optimized away giving the false impression that it
-works when in fact the libc might not support it.
-
-Update the check to a program that uses the stack, hence making a link
-fail if proper support isn't available, for example in non-ssp enabled
-uclibc toolchains like this:
-
-test.c:(.text.startup+0x64): undefined reference to `__stack_chk_fail'
