glibc: re-package for libnss-db

2.11.0

From: Jackie Huang <[email protected]>

On other distros like ubuntu/centos, libnss-db usually provides:
- The libraries
- The Makefile to create database
(in /var/db for centos, /var/lib/misc/ for ubuntu)
- The makedb command (it's in glibc-common for centos7)

What we had is:
- The libraries are in glibc-extra-nss
- The Makefile is removed
- The makedb command is in glibc-utils (lack of dependency)

So when glibc-extra-nss is installed but glibc-utils is not,
we see error like:
nscd[165]: 165 checking for monitored file /var/db/group.db': No such file or directory nscd[165]: 165 checking for monitored file /var/db/passwd.db': No such file or directory

And there is not an easy way to create these databases.

To fix the issue:
- Re-package the libraries into libnss-db
- Don't remove the Makefile and add it in libnss-db
- Add RDEPENDS on glibc-utils for libnss-db, and add RSUGGESTS on make since it's optional to generate the db with make.

Notes:
For external toolchain, an extra package 'libnss-db' need to be provided If replacing glibc from core.
