samba: Update to version 4.21.2

samba: Update to version 4.21.2

- Update from version 4.21.0 to 4.21.2
- Update of the rootfiles for x86_64, aarch64 & riscv64
- Version 4.21.0 mentioned that LDB is no longer available to build as a distinct
   tarball. However version 4.21.0 previously built without any problem so it looks like
   it was still available. Now with version 4.21.2 the lmdb package needs to be available
   or you have to disable all ldb options. As these options were uncommented in the
   previous versions of samba, it looks like they are intended to be present. To make
   this version support in the same way the lmdb package had to be moved so it was built
   before samba is built. Hence the shift of lmdb in make.sh
