samba4: bump to version 4.1.7 and improve cross build

Bump to the latest 4.1.7 version and improve the cross-build logic.
With the new patches the build is basically architecture-agnostic making
it possible to ditch the arch-specific cache to use a generic one.
Some toolchains might not be too happy with samba4 because of bitrot,
hopefully we'll find and fix or blacklist those with autobuilder help.

+Subject: [PATCH 5/5] build: find blkcnt_t size via array
+
+Using the same trick as commit 0d9bb86293c9d39298786df095c73a6251b08b7e
+find blkcnt_t size via an array so that it can be determined via build
+rather than running it.
