pimd: add do_install to pimd

The previous do_install is empty and do nothing.

Unset variables datadir and mandir, use pimd's default set.
So it could install doc files correctly.

ssmping: add do_install to ssmping

The previous do_install is empty and do nothing.

Tweak install doc dir, so the man doc could be installed to /usr/share/man
rather than /usr/locale/man.

postfix: create or update aliases.db when using systemd

aliases.db should be created by postinstall script, but failed since
queue_directory is not includes root dir ${D}:
    ------
    |newaliases: fatal: chdir /var/spool/postfix: No such file or directory
    ------
initscript will recall newaliases before start postfix daemon, the similar
method, which run aliasesdb to create aliases.db when using systemd, is
introduced to fix this issue.
