Add USE flags for nss-pam-ldapd and sssd

[bedroge]

Required by EESSI/gentoo-overlay#99. Note that it also removes a bunch of host symlinks that are no longer required due to the changes in both PRs.

This solves https://gitlab.com/eessi/support/-/issues/32, as it will make use of the host daemons.

The script added in commit 8523330 will apply all those changes. I've run it in our build container, and this is the (expected) difference in packages:

Note that it also recompiles glibc, adds some additional configuration, and bumps the commit used for the EESSI overlay (in order to get the changes from EESSI/gentoo-overlay#99).

This is the output from running some of the affected commands:

$ last

wtmp begins Mon Dec  5 01:00:00 2022

$ who
$ 

Note that it looks like who still doesn't work, but that's because of the container, and the who from the container itself gives the same result. Even more important is the following, which shows that the correct paths are now picked up by these tools:

$ strace who 2>&1 | grep "[u,w]tmp"
access("/var/run/utmpx", F_OK)          = -1 ENOENT (No such file or directory)
openat(AT_FDCWD, "/var/run/utmp", O_RDONLY|O_CLOEXEC) = 3

$ strace last 2>&1 | grep "[u,w]tmp"
openat(AT_FDCWD, "/var/log/wtmp", O_RDONLY) = 3
write(1, "\nwtmp begins Mon Dec  5 01:00:00"..., 38
wtmp begins Mon Dec  5 01:00:00 2022

The same changes have been deployed to the pilot repo, and tests with LDAP showed that this works fine now. See https://gitlab.com/eessi/support/-/issues/32 for some more details.

Nice work! Well documented and tested.

I've run the update script on both architectures, this is the (same) diff for both of them:
