ntp: cleanup recipes and fix SSL support

* Move common definitions to the inc file
* Drop override of do_configure which doesn't seem to be needed anymore
* Fold ntp-ssl into the ntp recipe as a PACKAGECONFIG option for those
  who want it (default to off) and fix configure-time checks to detect
  OpenSSL properly so that it gets enabled when selected
* Remove ntp-bin package and put its contents in currently empty
  ntp-utils package (with migration path)
* Fix hardcoded paths in ntpd initscript
* Specify ntpd.conf as a configuration file for packaging purposes
* Rearrange so that packaging definitions are towards the end in the
  expected order
* Delete unused "ntp" initscript file
* Add SUMMARY
* Update HOMEPAGE

This reapplies some of the changes from the original patch by
Morgan Little <morgan.little@windriver.com>.

ntp: make servers configurable and default to none configured

People can't blindly use pool.ntp.org, especially if they are building
for a product or something that could be used in a product, so at least
try to get people to do the right thing and not use pool.ntp.org by
default.

The previous network interface up script is now installed as
ntpdate-sync in ${bindir} (and symlinked as the network if-up script).
NTPSERVERS needs to be set in /etc/default/ntpdate.default at runtime,
or a different version of this file with a default value can be provided
in a bbappend. (If you intend to use ntpd you will also want to provide
an ntp.conf with the appropriate server(s) set there as well.)
